I am so drained because there is no resolution and Vodacom is just taking me from pillar to post I communicated through email and I was sent an email to go in store for assessment, on Sunday I went to Westgate Mall in store and the store advised they book for repairs and of which I had already stated that I do not want that, sent an email again advising what happened in store I am again sent instore for assessment and the store doesn't do that, who is the idiot?? Please contact me through email, I am at work and I need attended to asap
