Please bring back my services on my numbers

In March I had an incident whereby I checked my account balance during the day on my data account and it showed me I still had data and the data for the night express as well. the same day when I checked it again in the evening it said I didn't have any data anymore. I called MTN's call centre and they said it was still not showing @the time and asked me to check later. A month later I receive a bill of more than R3500 of which I normally pay just under R900 for my 3 accounts. when I enquire, I was told that it was this data account that used about R2700 in a space of about 5 days. I disputed this amount and asked for the data validation and Itemised billing in April. Up until today I have never received those but MTN has managed to close my services 3 times already. Every time I have to call the call centre and they open them. I'm still paying for my account but removed it on the debit order. yesterday I received an sms saying I must pay or else they will close my accounts in two days, of which I paid last week already. they closed my accounts today and that two days is still not even finished. THey know they on strike but they can't wait to close my accounts everytime without res
