Very bad attitudes from staff

I contacted Finchoice looking for a loan as they have been sending me letters and communication for their adverti*****ts. I spoke to the lady that they can debit from my account on the 31st as i get paid last day of the month. I realised immediately that the lady put in the wrong date when she was reading the terms and conditions to me. I immediately advised her of the error and she tried to rectify it but told me the system does not allow her as they are experiencing technical problems. The lady said i should phone the next day in order for them to rectify. I phoned the following day and i was put through to the supervisor by the name of Kevin who told me he wants to listen to the recorded phone first to see who made a mistake. He did listen and realised it was their agent who put the wrong date but never bothered to phone me back as promised. I contacted him again and he told me he did put it on the system that it was an error. To my surprise i have been receiving more that 20 calls a day from their agents threatening to take me to credit bureau. I tried to explain to the agents but none of them wanted to listen to me and they keep on dropping the phone. People be careful of Finc
