Unallocated payments for 4 months now going to 5 months

I have spoken to about 5 people since January regarding my unallocated payments to date, who have said that they allolcated my payments, others would say they have escalated my matter, yet fail to get back to me with an update. I have been liaising with Jabulile Sindane from the Credit Control department, for the past week or 2. She has mentioned that she sent through my proof of payments to the allocation departments however has not received an update on why the rest of my payments have not been correctly allocated. I have been receiving threatening emails from your legal department, and at this point its not because i made no payments, but because someone in the allocation department is unwilling to allocate my payments. Jabulile tells me that theres nothing she can do to get through to the allocations department as she is not allowed there. Even if this mean my credit gets ruined, theres nothing she can do about it. I am failing to understand how someone is unable to assist a client. May I please get assistance with this matter?
