No Assistance and no resolution to their mistakes

I have been in contact with them since start May about an incorrect debit order due to their invoice template not adding up correctly I get charged the correct line item R479 for home unlimited and then their template goes al wack and gets just under a R1000 subtotal to make final amount due over R1000. have been n constant contact through their support link those reply are terrible they don't even understand what you say and blame it on you as well in once instance. i then tried raising the issue with them on face book at long last the media consultant rep**** and raised a ticket, I got credited once for the May debit order and then it happened again june and July still no resolution even when my broadband reported it the CEO said they are correcting well nothing is happening on my account again see that i can expect a R1000 debit order 1 Aug for a R479 product as per my dashboard today, No one answering me anymore not even the marketing agent on facebook. i have requested my account closed down perhaps they will reply to that. i understand high volumes but i have not been answered by their general support after raising numerous tickets for more than 2 months now. Their customer support is horrible to say the very least which i could give negative star rating, very disappointed as the beginning with them was smooth and seamless even my migration all downhill from there
