Bad customer service

My complaint are as follows:I <br> took my Tablet to Vodacom on 18 May 2015 but it was confirmed that the tecnician only recieved it on 29 May 2015.I was given a quote of R605 for repairs but received my Tablet back with the original problem Your consulltant at Vodacom Mountain Mill was very evasive and hardly gave me any feedback and to make matters worse: I then reported this matter to Shavonne Miller ( Field Service Consultant - Western Region). Shavonne responded on 19 June 2015 and further cc'd me in an e-mail to Guy at vodacom Mountain Mill Mall.I have extensive phone bills due to enquiries I made to Vodacom, including Vodacom Customer Care where I received the same response. I must take this matter up with Vodacom Mountain Mill Mall.After all this I request that my tablet must either be replaced with a new one or that my contract must be terminated with no further cost to me. I experienced the worst customer service ever and thus demanding immediate feedback. Today I have no tablet or any response on numerous e-mails sent to them.
