17 DAYS TO ALLOCATE A PAYMENT AT MTN??

I am very upset with MTN. I made an EFT payment on the 1st of April. I've send the proof of payment through to multiple consultants on multiple occasions for them to allocate the payment to my account. Up until today no allocation has been made to my account. I am due for an upgrade and now they cannot assist me because my account shows an arrear. They say they will help you during the lockdown but it takes 3 weeks, multiple emails and phone calls just to allocate a payment???
