Ineffective & inefficient service

I have in the space of 29 days logged the same issue on WhatsApp with FOUR different agents and it's still not sorted out. I also wrote an email to the complaints department on 17/06/2021: followed up on 23/06/2021 & 28/06/2021.

I need a credit note for the R404 that was debited wrongly on my account on 01/06/21: I gave the sales agent written instruction that I will be continuing with the MTN LTE instead of the Telkom LTE on 21/05/21. The cancellation wasn't processed: I enquired with her again on 31/05/2021 and on 01/06/2021 about the cancellation, as I can't cancel it on my online profile because the package that we had discussed and that I communicated to her that I will be proceeding with, included the usage of my current router for a R50 levy p/month.

My Telkom LTE was last used on 28/05/2021.

Thereafter, I logged the issue on WhatsApp: 1) Iman: 01/06/2021 - he said the Telkom LTE needs to be cancelled by the sales agent and the cancellation backdated in order for me to get the refund. I was told I'll receive the credit note the next day (see screen grab attached) 2) Thapelo: 04/06/2021 - he said I should just wait a little longer for the credit note (see screen grab attached) 3) Sibongile: 10/06/2021 - she said she logged the request for a credit note. I followed up with her on the same day, as I havent received it (see screen grab) 4) Masindi: 11/06/2021 - she said the credit note was declined but she logged it again with good reason (see screen grab attached). 5) Mmabatho: ***1 - she said the credit note was declined but she logged it again with good reason (see screen grab attached). She couldn't tell me what the reasons given was.

This, is extremely frustrating: I can't escalate it because everyone tells me they 'put the team on it'. The team hasn't done anything yet, and 4 weeks into it I still haven't been helped. The credit note that is owed to me, because I told the sales agent on the phone and in writing I'm going over to the MTN LTE (due to a move).

I shouldn't be held responsible or liable for a mistake made by the sales agent.
