Incompetence by multichoice

I paid my account on the 22nd of September Sunday BUT I woke up this morning with an annoying message saying that my account was deactivated due to the payment not made. How dumb is that. I normally pay the account without having to send the proof of payment to them BUT I spoke to a rude agent agent by the name of Xolie who told me that I was supposed to send a proof of payment to them. A very poor service that multichoice is having now, I don’t what gotten into them. I need help plz. My account number: ***3, plz I need my account activated as soon as possible
