Disgruntled and dismayed.

I called Vodacom in December as like everyone, I get paid earlier that month, so I called my debit order and I specifically advised that this is just for December, an invalid debit order has gone off on my account on the 15/01/2021 which resulted in me being charged by my bank and now, after the mess that took place in January with my debit order, I paid cash on the vodacom app on the 25th, only for the debit order to go off, after I was specifically told by an agent that it wouldn't, hence I made the payment. I have now been waiting since the 25/01 for my refund and I still have not received it. I was told that the money would be in my account by today and now I've just called and was told that it would take 7 working days!
