BAD EXPERIENCE

Currently a tenant at City Building under Mafadi, moved in month end March, I viewed the apartment, the Agent made showed me a showroom which he did not disclose that it was a showroom, i liked it and paid all fees said, got my lease with rent being R1900 excluding utilities, i told the Agent that will be moving in on Monday and to leave the key with security since i will be knocking off late, he assures me that the key is with security, i arrive with my furniture and ask security for keys "He tells me there is no key" i call the Agent and indeed no key was left here, had to book in a hotel. the next day i get the key from their office, now i am ready to move in, i am told that the room i saw is a showroom, ok i understand, i get another room which is very bad compared to the showroom, ok i move in. comes the 25th April, they bring and invoice with triple the rent money "rent is now R2200 excluding utilities". ok i pay rent on the 26th, now on the 30th April i come from work only to find that my room's lock has been changed, for what reason i dont know, none called me or emailed me anything. if i had not paid rent i would say that might be the reason, but i paid rent which is higher than my contract. Only if i knew how the minds of these work maybe i would understand. but i am obviously reporting this to the housing tribunal.
