Cosmopolitan projects are ******** people

I recently app**** for a house at cosmopolitan projects and one of their agent assisted me his name is Masilo Nkwe, we told him that we want to extend this house and add a double door garage he was quick to says yes the yard is big enough to add you double door and you'll be able to extend the house as well, only to find out that we couldn't add even a single garage at all,He Masilo referred us to one of his house planner but that guys quickly said this was impossible to be done. They is no space for extending here, and I just felt like I got ****med by cosmopolitan projects here, I advise them that I will no longer take the house because it's not what we agreed on and they must please refund my Deposit back, I was told I will be getting my deposit back buy one off the agent who called me but a 10% amount will be deducted, after this the agent tried to convince me to sign and also send them my documents to do a reassessment I refused because the house is not what I was sold, nw I don't get respond from them and I want my deposit back
