My heart is broken

I have obtained a bond with Nedbank last year and I wanted to start a day care centre. Since last year October I have been calling and going in and out of the branches in order to get help from Nedbank. As part of the application I need to get a letter from the bank before I can get a special consent. Therefore I have tried getting help from nedbank but whenever I called I’d be told that my quiet has been lodged and I will get a call in three days time. This was in October 2023 and every time I’d be told of the three days but I wouldn’t get that call. Three months passed and I then got an email to say I should answer few questions which I did then I was called in into the branch and I went they asked me to submit certain documents I do but then after that they tried to peruse me to rezone the property I said but the city doesn’t want me to rezone then they said they need to send an evaluator before they give me the letter and also that took forever and I’m made to pay for the evaluator myself , thousands of rands. Then since they have gone quiet and I don’t even get an update. I keep calling time and again with no help available. The whole process is stuck I can’t even start the day care because nedbank has decided to not give me the letter and also they have gone quiet. But every months I’m expected to pay R20000 for the bond. I can’t even do anything and can’t stay in the property either. Please help.
