Refusal to repair handset

Unfortunately my Vodacom cellphone account was with Nashua Mobile, who has closed down. They transferred their Vodacom clients to Vodacom direct.<br> My Samsung Galaxy SIII mini suddenly lost use of the external speaker (therefore no sound)<br> I gave the phone in at the Liberty Midlands Mall vodacom repairs in Pietermaritzburg, 1,5hrs drive from where I live. Just to return a few weeks later to be told it is not a vodacom handset.<br> I then returned about two weeks later with the proof of purchase stating that it is a vodacom contract & handset.<br> The phone was sent away for repairs with this information.<br> When I returned a few weeks later to collect my phone after receiving an sms stating that my Job no. ***9 is ready for collection, I was AGAIN told it is not a vodacom handset, therefore nothing was done to repair the handset. And I drove 1,5hrs just to be turned away with NOTHING done!<br> The lady who assisted me in the vodacom repairs shop just shrugged her shoulders and said sorry.<br> What am I supposed to do with a permanently silent phone (that I am still under contract with) and the service provider isn't interested in helping me!? <br> Am I supposed to stop paying as they stopped servicing??
