bad service provider

I took out my cellular contract April 2016 they always debt. My bank account since August 2016 it just stopped. I only find out that my account weren't debt when they cut of my phone. With a long argument with the call centre I've decide to eft them each month. Which is only 99.00 pm I pay R100. I don't get an statement at the end of the month because some times I buy n data bundle of R10. So I have to make note and remember. I also did asked them on more than one occasion to please send me a statement. Just don't get one. On the 7th of this month Mr p mobile phone me because my account is not payed i payed my account on the 5th which were a Saturday. I've told the lady that I did make an eft payment of R100 she rep**** that I still need to pay 31,00 or I will be handed over. I asked the lady how in the he'll must I know what I have to pay without a statement or sms or something I did pay. Today I wanted to make a phone call. My phone has been cut of. This is bad. Because of 31,00. And it not even my fault. I will never even recommend Mr mobile to anyone. Can't wait for next year April. To cancel my contract. My pay as you go is Vodacom I will rather stick with them
