After being contacted by Vodacom after last review I was contacted by Vodacom to resolve my issues, I was promised immediate release from my contract and that my fibre line would be released that I may go to a new ISO to have my issue sorted. I have since moved over, my new ISO sent a technician out, within 24 hours and repaired the line. Something Vodacom were unable to do within 5 weeks of daily calls, requests and escalations to the Vodacom technical team. But the line has not been released as promised and I am unable to move ISPs. Vodacom claims that don't have the ability to manage the release as the line it's no longer with them. Vumatel has confirmed the line is still active with Vodacom. So again I sit at the mercy of Vodacom. With no control, zero customer service, and a company that is absolutely unwilling to assist there customers.
