AFTER 23 years being a customer - Worst customer care EVER!!! SHAME ON YOU CELL C!

After 23 years - Cell C clearly don't care about their clients - I've been trying to change my banking details with Cell c for the past 3 month - but the people that is placed there to help couldn't change my details the 1st time, the 2nd time they only changed the bank name - and the 3rd time - after I had to phone every single time - pay eft - every single time - paid penalties - every month - the 3rd person got it right - then again it was to late - so No I don't think it is fair any more to charge me the penalty fees - and Your *********** people cant help or listen to the previous recordings - see that you made a mistake - take the penalty fees off my account and all is well - NOOOOOO!!! YOU PHONE ME AND TELL ME IF I DON'T PAY THE PENALTY FEES YOU DISCONNECT MY LINE - AFTER 23 YEARS - THIS IS THE WORST SERVICE EVER!!! I phoned and tried to speak to a superior - NO LUCK cause you don't care about your customers - you can ***** them over month after month and they have to pay or you disconnect - well I will NEVER AGAIN recommend Cell C to ANYONE!!!
