NO RESPONSE TO MY COMPLAINT OR WILLINGNESS TO HELP

I logged this complaint with MTN on 24 Feb & haven't received any response! I came over from Nashua Mobile where the due date of my account was the 1st of every month. I noticed that on MTN it is the 22nd. When I called it was explained to me that this is MTN's business rules, but no one advised me of this! I thought it was just a mistake or something. When I was informed that I cannot change the date because I am a cash payer, I asked to be put on debit order because I don't want this nonsense of my account being in arrears by a few days every month, only to be told that I must first pay my account on time for 3 months before MTN will put me on debit order! This is the most ridiculous thing I have ever heard! I was not impressed with this call centre agent in the least! I don't get paid on the 21st, I get paid on the 25th like most people, how do you expect me to pay my account by the 21st?? Don't you want my money & business? This is ridiculous! Can someone please contact me to put me on debit order?? It would've been different if this was a new contract I opened & I was aware of rules, but I was forced into this move and now subjected to this rigid attitude & business rules.
