Vodafone tablet malfundtion 3x in 3 months

<p>i received my tablet back after repairs, it was sent back twice because it still did not function after the first repair. I eventually received it but only used it for two or three hours and the same thing happened. It switches off suddenly and then the on/off button does not work, nothing works. I have again contacted Vodacom but to no avail, not even an acknowledgement to my e-mail. I sent an email directly to the person, Mr Lesley Abels, who, at last, assisted me with my previous complaint(s) but he is not responding. I would like Vodacom to cancel my contract and pay my premiums back, from March to now, as I had not joy from this tablet at all but am paying for it every month. Regards</p>
