WORST Service, blame shifting in the same company.

Such BAD customer service. I arranged to pay my account early via eft, i CALLED the call centre to confirm that this was in order, they agreed and said I can do the EFT, I paid them via eft on the 21/11/19. On the 29/11/2019 i upgraded one of my lines via the call centre and was told delivery of the new phone would be in 5 working days. Today, 06/12/19, I call to query as no phone has been delivered, to be informed that my account is an arrears due to a late payment penalty. After a useless conversation at the accounts department whom denied any and all help and blatantly blamed client care for the mishap, he insisted i talk to client care AGAIN... Who then wanted to put me back to accounts... Utterly useless. Eventually I was told a team leader would escalate via email for them to immediately clear the fee and update my status so my phone can be delivered. Alas, that was at 8am this morning. I call now again, 13:20,for a change a lovely consultant, but also unable to assist at all.... The people i have dealt with today, apart from the final young lady i spoke to, were rude, and incredibly unhelpfull. I wonder if il get ANY feedback today..... A companies incompetence causes me to waste time and money of their mistake.
