LOYAL CUSTOMER UPGRADE DECLINED!!!

After 15 years as a MTN customer and with 6 open lines, I am now declined for an upgrade because I had to go under debt review. And yet MTN is not part of my debt review and I pay with a debit order and I AM NOT IN ARREARS. Does loyalty and being a long standing customer who pays on time not account for anything. I GUESS NOT!!! Their is not even a motivation or appeal process . . all that is left is now to cancel all my contracts as they become due. I am deeply disappointed and I am sure they will be losing customers due to their rigid processes. They certainly dont care about the customers who have been with them for so long.
