Horrible and unfair service from African Bank

Some time in August 2021 l received a call from African bank asking if I wanted a loan. As I was looking at starting my own business I saw this as a great opportunity. The application for the loan was done on line and I was asked asked to submit some documentation which I did. The loan was approved in no time. The contract process was also done online and during which I was offered an offer of a cell phone to the value of R7000. I took the offer, l was informed that the cell phone will be delivered within 4 to 10 working days. The same day the funds were released minus the cell phone amount. The 10 days passed and l decided to follow up on the cell phone. To start with they had a wrong number and they attributed that to them not being able to contact me. Mind you it was African Bank that made the initial contact, how they now have a wrong number to my account bits me. Following this l received about 3 calls from different people assuring me l would get my cell phone. The 4th call was to tell me that, the initial phone that I had chosen was out of stock and hence they were offering me another cell phone. This was a cheaper phone by R5000. I then enquired if I would get a refund of the remaining amount and the answer was no. I felt cheated and I refused the offer and indicated l would wait for the cellphone of the amount they took from me. Following this call I received 2 more calls with the same offer and each time I would refuse the offer. On the 4th call I told the operator to please cancel the order and I get the refund, to which I was informed African Bank would contact me to that effect. 2 weeks went by, no contact from African bank. I decided to send an email narrating the ordeal, no response. I then made a call to follow up, the operator who responded wanted an authentication process to be done which I have no objection to. However no sms came through, we tried the questionnaire authentication. That failed and I was told l could not get help. I am really disappointed, it was African Bank that contacted me and now I have to waste my money and time running after them to solve the problem they caused.
