MTN reminder to pay account **** TO ME! Suspended account!!

Hi there. MTN for some reason cancelled my debit order for my contract a while ago, so I have to pay online every time. So this month I forgot, as any human does from time to time. So on 11 March, 12:54, they sent me a reminder to pay R344,25 or they will suspend my contract, WITHIN 2 DAYS. I immediately made the payment through their website, thinking that if it takes 2 days to show, the SMS says it will be suspended only in 2 days, I thought I was safe. THE NEXT DAY, 12 March, 09:04, my account was suspended. LESS THAN 24 HOURS!! 13 March I phoned in. The guy said he can't do anything because I have to phone from the number that has the issues, and the more I explained I can't do any outgoing calls, the more he refused to help. Then I decided to put the phone down and dial again to speak to someone else. Finally someone that tried to help, she explained to me that the money does not show yet, and if I can send her proof of payment she will help me, she gave the email address of ********** , I sent her all and I never got a response. End of the day I phoned in again asking if I could speak to her again, which the lady said they can't transfer to colleagues, which is ridiculous. So right now it's 14 March, 09:30, which is 3 days later and still a suspended account and a very short fuse left. Oh and also almost everyone in call centre I spoke to refuses to put me through to a manager or someone in charge. I understand I made a mistake, I forgot to pay, but when the reminder came I immediately made a payment. If you have a payment thing on your website, make sure that it shows when a payment is made and do not suspend an account on a paid contract. Or give me a better suggestion to pay to clear it immediately if you guys want to go 'suspend-happy'. DO NOT say pay or we will cut it off in 2 DAYS, and then when I paid on your website thinking you'll see it, BECAUSE IT WAS DONE ON YOUR WEBSITE, and then suspend it only 20 HOURS after the SMS was sent, that's lying! Hopefully this message finds itself to a manager or someone that can sort this out and take the suspension on my SIM off and do something helpful. I've got people to call and data to use. HELP ME!
