I have had issues with my dsl line since December last year... I have been escalated complaint upon complaint and eventually I decided to cancel my line due to pathetic service and delivery. I have escalated a billing related query to *** and *** and to date no response from them. My reference no : ***2. I do not have any contact details for them and neither do I have any names for them and I am told there is no contact details for them. I am receiving calls that my account is handed over and yet my issue is not yet resolved. I have 3 other contracts and I pay over R1500 for it which I will be canceling as well due to the disgusting service. Can someone please call me urgently!!!
