Pathetic service

I cancelled my fibre with Vodacom a month and a day ago. Since I had no contract with Vodacom, I expected the fibre to be cancelled immediately, but they held me hostage for 30 days. Yesterday I called to enquire about the cancellation, as it was the due date. I requested an email confirmation regarding the cancellation, which I have still not received! I phoned this morning and could not be helped due a "systems error". Vodacom's service is useless!
