Vodacom unsufficient service.. Bad customer service

Ive been with Vodacom more that 10 years never missed a payment.... then this year 2 of my lines was upgraded withou my consent, and i was only informed when i upgraded my other 2 main contracts.... i phoned the customer services and reversed the last 2 upgrades and logged a inquiry how my other 2 lines can be upgraded without my consent.... a few days later i was informed all was reversed. I requested a cancelation of all my contracts as the contracts is ending 11 November to give them the required notice... so this was August and the consultant informed me that i must phone 11 Oct to give a months notice... so i phoned 11 Oct ... just to be informed 2 of the lines was not reversed... so we logged another inquiry and i am still waiting... i am also stil waiting for proof of cancelation.... THATS WHY I AM LEAVING VODACOM... BAD SERVICE
