MTN will NEVER see me again.........

<p>I have 2 contracts (inexpensive) at Mtn for my children for about 7 years now and always had a debit order on them I went to upgrade one about 7 months ago........within this week I got a call from a company telling me that I owe the the full amount on my mtn contracts .........I am so disappointed and angry. As this is a fault on mtn side for not reinstating the debit order when I upgraded with no warning by mail or phone handed me over and I'm now listed as a slow payer .......I contacted customer service they said there's nothing they can do for me to go back to the mtn outlet where I opened the account.......when I got there today they said SORRY the accounts been close...........this is ridiculous MTN I will pay you but you will NEVER get my business again. And I demand some answers!</p>
