Failed to meet customer needs yet other companies were able to do just a quick and simple change of banking details

Very much disappointed with cell c customer service on contract department, I had an issue with my bank where a ***** took place on my account and while investigating they've changed account number into new account number then they moved all debit orders into new account number but cell c failed to respond to my bank other companies were able to send debit order mandate and to date all my account and policies are up to date except CellC u call and ull be moved from pillar to post instead of fixing the problem I'll be given an easy pay number which is also a challenge in stores I have given up on cell c because wow 😲 their service is so poor or maybe it can be fair if cell c can move their business and find another agent that could service their clients better because the current agent "Merchants " it's failing us the customer's with flying colours I'm in arrears yet they have the account number in the position but are failing to action a debit order u call the customer service using your contract SIM their system prompt u to enter number in question lol ended in prepaid department then the agent refuse to transfer u before he does security check and ask nature of problem by the time u get to the relevant department u tired and u have to start fresh and explain your problem to this day I have not been helped and Merchants team leaders don't wanna attend the calls they surrender most of the work to agents on the floor then u ask for the senior "Ops manager "in the unit forget they can only take your details and another team leader will call you.

My account is still not up to date in arrears because they don't want to action my order and debit my account as a result my aim is suspended and may they fix the issue and revert back to me

In closure can Cell C as the service provider opt for new service provider to handle their affairs because wow Merchants is failing us 🤔
