Terrible Service!!

This is now the 3rd time i have to complain on hello peter about Vodacom and their service! It is now 7 months since i sent my lenovo tablet in for repairs and still no joy!! After the second complaint, Fabian from Vodacom gave me a call and the tablet was sent from only they know where to Cape Town. Now Cape Town says they cannot fix it. I have emailed Fabian 3 or 4 times in this last week but he does not call or respond to emails!! 7 months without my tablet yet i am paying for it!! Where is the customer service? Where are the feed backs? Where are all the promises made? I read an email that was sent to the store by Fabian telling the manager that \the customer must call the repair company himself!!"???. Is that what is service about? I got my warranty through vodacom"
