Broadband is privately contracted, how to break it?

This situation is more common in residential areas where developers or property companies have good personal relations, helping them to exclude some operators, not allowing operators to enter in order, and only allowing the network of an operator who signed an agreement with them to enter. This is to seek illegitimate interests at the expense of the owner's right to choose, which belongs to unfair competition. Owners can unite to correct this mistake through the industry Committee or the owners' meeting, and the property company will change the property if it does not obey.
