How about Longguang Jiulong Lake? OK or not? Is it worth buying?

On August 31st, 219, I went to Foshan with the property consultant of Q Fangwang to look at the house, and saw the property of Longguang Jiulong Lake (real estate developer: Nanhai Longguang Mingjun Real Estate Co., Ltd., Foshan City). When I arrived at the sales center of the real estate, I was hesitant when I saw the real estate. They said that I could pay a part of the earnest money first, and that I could get a full refund at any time when I didn't want to buy it. The developer of Longguang Jiulong Lake found their colleague Liang Chengze's card, and asked me to transfer it to Liang Chengze for 5, yuan to help me pay the earnest money (I was a little confused at that time why it was a personal account, not a company account, but I thought that the developer was so big that there should be no problem, so I transferred it to Liang Chengze). Before Liang Chengze could transfer the money to the developer of Longguang Jiulong Lake, I felt that the property was still a little far from my place of work, so I decided not to pay this earnest money on the spot and didn't want to buy it. Then I asked for a refund. Therefore, it is not a sincere gold at all, but consumers are unwilling to buy it on the spot. The real estate company also promised a refund on the spot, saying that a penny would not be less. They thought it was a refund operation on the pos machine, but it didn't succeed, and they gave a statement that they couldn't get a refund immediately because the time was later than 23:. My question is that since Liang Chengze's card was found by the developer, I don't agree with the purchase on the spot. I don't know the password of his card, so how can I successfully pay the developer? Moreover, I had to sign the payment at that time, and I made it clear that I would not buy the house, not to mention that it was Liang Chengze's card. What name should I sign? Later, I called 11 and asked the police for help. After the police arrived, the real estate company said again in front of the police that it would definitely refund. Because it was too late, I agreed to their refund process because I thought that the police were present anyway, and I was confident that they would say so. The real estate company told me to go through the refund formalities on the morning of September 1st the next day, and then said that the refund process must sign the contract of sincerity fund (I was unwilling to sign it myself, and the so-called intention fund was signed under the pressure of the person in charge of the developer at that time on the grounds of not signing it, so I wouldn't get a refund), saying that otherwise the finance could not be refunded, and the person in charge of the real estate company explained to me that the contract of sincerity fund stated in black and white that customers who didn't want to buy a house could get a full refund. I didn't want to sign this at first, but the person in charge of the real estate company said that the refund process could not be processed until this was signed. Later, when I signed it, I was told that they would handle it urgently and wait for a week or so for a refund. Half a year's savings have been hollowed out, and now rent and living expenses are problems. On the evening of August 31st, when the police were there, there were videos, and the person in charge of the developer said that it could be refunded if it was expedited for one week. I called to ask about the progress, and the other party lost his temper with me, very impatient, and obviously had the meaning of deliberate procrastination. Now there is no specific refund time for consumers, which is vague and there is no clear refund time limit. The witness and physical evidence are all there, and the police uncle is there to understand the situation (the developer promised to refund in full in front of the police, and the refund was expedited for one week. Now there is no progress in the refund of the developer, and a bad check is issued. )
