Allocating of payments

I had a contract with CellC 2017 due to unforeseen circumstances I lost my job and I had to move back home so I could not continue with payment of the contract. In 2022 I app**** for NYDA funding as I am in business and my ITC score indicated that I owed Cellc ,I then called the service centre requesting assistances on how I should pay my account going forward of which a call centre agent sent me a Cell C account number with a ref no that I must use whenever I made payments. I then utilised that cell c account number with the specified account number that was given to me by one of the Cell C’s call centre agents only to find that I was paying into the wrong cell c account because my payments were never found. I then contacted cell c again trying to get assistance in allocating the payments of which I was assisted by a lady who told me that the accounts department is busy allocating my payment and an interim payment will be made into the correct cell c account till today I am still waiting. I again emailed the cell c customer care email trying to query my account only to get an automated response and no one bothered to follow up on my case. The lady promised to follow up my case to see if the accounts department has allocated the funds. I am pleading for assistance as this badly affecting my credit score
