No Accounts received due to red tape issues

Three cell accounts with MTN. One In huge credit I receive an account for every month. When I request for the second one which I was receiving till two months back then it's red tape. Don't even talk about the 3rd account. I pay it on the cell number for a year now due to no account number because since I have purchased a year ago never received an account and when I request it's red tape. I asked for it to be escalated for attention but still no response.
