Pathetic service

I request for credit relieve with RCS for the months of June and July because of covid19. I got feedback that I was granted this request. End June they deducted the installment of R1090 approx. I called them on 1+2/July and they admitted to be wrong. On 16 July I made a follow-up call because they said my money would be refunded. A supervisor told me that from the 2/7/2020 it will take 14 workdays to be back in my account and apologized so much. Also said she will mail me forms to ask for another months extension as for end August. Never got any mail. Money was never put back in my account. Come end July again they took a installment off although I was assured by this lady on 16 July it won't happen.installment approx R980. Called them again on 28/7/2020 and asked them why they deducted. Said they will look what was wrong and called me back. Call was made 09.07am. Never called me back. I drove 10 km to a Game shop to use there phone as my calls for the calls to them was in excess of 1 hour and 10 Min. Was then online with a lady for 40 Min and she came back and said she spoke to management and the credit people and I must fill forms in to be refunded. I told her it's unacceptable and wants to speak to a supervisor. She said the supervisor would call me in 10 Min time but never did. Only the next morning she called back and said now I must go to the bank and get statements of when they have deducted those installments. I had to walk to town as my wife had car. 2 km...63 yes old...told her but she said no other way. Send statements through and she said she will pushed it for as soon as possible. I don't believe their lies. Sure I will wait another month for another excuse.my phone Bill alone was over R200
