Pathetic and extremely dissapointing service

Bought a Samsung Young 2 in June 2015, 24 September 2015 I took the phone back to Jet as it does not charge anymore. Melanie took the phone explained the process of repairs promised to send it away and that I will wait max 6 to 8 weeks. After 6 weeks i phoned the store to find out about the phone Melanie said she will check and phone me back she never did. Today 20 November 2015 i phoned again she promised to check and phone me back again she did not. I went to the store and asked about the phone. Waited almost 20 minutes for feedback. Finally when i got feedback Ashley brought the phone and said Vodacom did not send a report so he does not know if Vodacom repaired the phone, took my repair slip teared it up & said I should check at home if it works. Got at home phone was never fixed. I phoned the store spoke to Ashley explained that the phone was not fixed and asked if the phone was sent away for repairs he tells me they cant tell me if the phone was actually sent away for repairs. I was furious & dissapointed as i waited so long for nothing & what now i must take the phone away again not to be sent away at all & to be told by someone that works there they cant take responsibility
