Abusive customer service

Very bad service bordering on customer abuse. I requested 3 quotations for early cancellation from Vodacom and made the payments as quoted and sent back all the required documents.I have been calling these people over and over to confirm that this will be done.I had to call over and over as I had same experience of a bad service previously.Despite assurances that this will be processed,almost 3 weeks later nothing has been done and they went into the money paid for cancellatios and set-off this month's (July) normal payment.Three weeks of calls over and over to remind them.

I have made the normal payment again and want these 3 accounts to be cancelled as quoted.This is the most carefree ISP.
