Telkom not sending my upgrade phone yet still deducting.

Good day

I had a contract with Telkom which was ending in February 2020, I got a call in January that am due for an updagrade, I asked the consultant to call me on a Friday because I was in a strat session for 30 and 31 of January, another consultant called we spoke and arranged for a new phone which I said I wanted a Y9, and concluded a call with the agreement that it will be delivered at my work place and the debit order will continue as it was, 2 weeks later I call to check because she said it will take 7 days for them to deliver, the guy I was talking to said there are no notes of on the system that shows I spoke with one of the consultants however it still shows that am still due for an updagrade, he helped me promising that the phone will be delivered, early March I called again and asked, same story that nothing shows that I wanted an upgrade, same thing again going through choosing a phone this time around I was choosing a different phone P30 lite, I waited and until now yet they keep deducting different amounts every month since February, even when I call trying to find out about the upgrade still no information yet debit orders are still taken, I did reverse a few debit orders but am worried about my credit record.
