Bring back my R749

My debit order didn't go through on the 1st of February 2020 as there were no funds in my account, I later got a statement from Telkom stating that they'll double debit on the 1st of March, a few days later I got a text stating that I must pay within 48 hours with payment details of which I paid R749 on the 12th February 2020 at 10h05 via eft to their absa account. My services got suspended on the 27th February 2020 and I called contact center where I was told that my payment hasn't reflected and that I should forward my pop as it takes 48 working days for that department to get back to me, on the 1st of March, they debited R1498 and my services were still suspended till the 2nd. I called the contact center again seeking answers and I was told that the reference I used was incorrect and I explained and advised that I forwarded the pop yet nothing has still been done with regards to getting my refund and they don't seem bothered at all. My last call on the 3rd gave me hope as I resent my pop to the consultant and she said I should give them 24 hrs and they should get back to me. 72hrs post to the call and my query has not been attended to, what do we call such service. They are quick to threaten yet are slower than a turtoise to refund their customers or is this another way of making us angry, tired of calling and not wanting our monies back.
