Payment

I have purchased a Laptop, my first installment was due to end of September, I did make a payment on the ABSA App, the only Beares that I could find is Durban. When i sent the pop to head office, they said they cant trace the payment. I went to make to reverse the payment, the bank advise I cant do it, because it was a EFT. I went to the Welkom branch on Saturday morning, 9 October 2021, the area manager of Beares was at the store, when I asked him to help us, he was rude and said to us, we must make another payment, he cant sorted it out, because we were at fault. We as a customer cant sort this out, because we dont have the people at the financial department telephone number etc. I feel if you want to give the customer good service, you must sort this out. The area manager actual was screaming at us and he also said to us, if we dont make a payment, he will repo the laptop. I feel this is unnecessary, if he want to i could help
