Big promises but no service from Vodacom

After my previous complaint about Vodacom, Marley called me and acted like he was going to sort everything out, but needless to say, the 'new' phone is back in for 'repair' and I get no feedback from Marley or the Vodashop in Bredasdorp or Vodacom. The new phone was delivered on 21st May, went in for it's first repair on 7th June. 18 days later it was returned to me and stopped charging again 2 days later and was once again sent in to the Voda shop in Bredasdorp on the 27th June, where it has been since. I have requested a job # from the store to give to Marley, to no avail. Vodacom keeps sending emails saying the job has been 'ended' - whatever that means. Samsung has contacted me to check if I am satisfied with the repair, but I don't have the phone back to answer the question! Terrible service all round and I am left with no phone and no feedback/contact. I have requested a new phone, since this phone was brand new but is obviously faulty, but because the fault first appeared after 7 days, it goes in for 'repair' and Vodacom refuses to replace it. Sadly, I will be stuck with the phone for 2 years. I will not be renewing 4 Vodacom contracts in my name, as they come to the end of their contract terms - I'd take my chances with another service provider who can actually do 'Customer Service'. Vodacom and the Vodashop in Bredasdorp are both seriously disappointing for lack of communication and feedback, never mind actually sorting the problem out to the customer's satisfaction
