LOCKED OUT of a unit that I paid for

City Property locked me out of a unit that I am renting at Tali's Place - this after I had timeously sent them the confirmation of payment and had requested my bank to clear the funds immediately. Payment was made on 27 November in the morning and I sent the proof of payment to City Property and to Melody (at the JHB) offices to forward to the credit controller (Rachel) and I also requested that I re-gain access to the unit on the same date. That evening, I proceeded to the building but was denied access to the unit even after producing a copy of the payment confirmation to the building manager. He then contacted the credit controller who was rude and with a stinking attitude - she said I should have made an effort to send her the proof of payment (something I had done) and that I should have called (something I had also done and left a voice message) and that it takes 2 days for an EFT to clear (I tried to let her know that I requested immediate clearance, but she was taking none of that). Seeing that there was no way she would be willing to help, I had no choice but to leave the building and seek accommodation elsewhere. I have sent a complaint and no contact has been made...
