Total lack of customer service.

I upgraded my 4mb DSL to 8mb. It has been a month now and my line only syncs at 4mb. Long story short I have been given the run around by Telkom because the New Sales department captured the Uncapped portion of the profile as 4mb. Countless calls being bounced from department to department and with probably 20 faults logged, it is still not sorted out. My question is, in this day and age with the economy the way it is, how can a business expect to survive with this total lack of customer service. No one ever gets back to me to sort out my issue. I am simply going to cancel my debit order for the month and when they call me to ask why the payment has not gone through I will address it. I am sick and tired of paying my hard earned money to a company that simply doesn't give a damn!
