Never ending list of problems

Firstly, I had to wait 3 weeks for the necessary to be installed at my residence. Darrel, the sales person never responds to emails or phone calls and thus problems were never solved. A week went by (after the installation that cost R999) and R200 worth of airtime later trying to get in working, the internet was eventually up. This was on the 24th of the month. They then had the audacity to send me an invoice for half a months worth of my contract fee for 6 days for apparently 1.2gigs, time during which I was in Knysna on holiday. After phoning Darrel, he said that he would speak to the accounts department so that I would not have to pay this amount. In addition, I was informed that because of something Darrel had not done I had to do a direct deposit for the upcoming month instead of the debit order going off automatically. On the 6th of June a debit order went through for half a months contract fee that was supposed to be wiped off my account!! I phoned that same day and spoke to someone in the accounts department who said she would speak to Darrel and her superiors, I have not heard back from them yet. Don't even get me started about the fact that they throttle you considerabl
