Fabric fault new cotract phone. No service

I'm ****p for vodacom and shop workers. Nice to sale contract, but \NO SERVICE"<br> I upgrade my contract in April and receive a Samsung Prime Core cell phone. The cell phone was from the beginning faulty and was reported in the 7day period at the Vodacom shop in Middelburg mall. I spoke with Kim and Billy the manager. I took it back after the weekend because I was on standby. They send it in for repairs and were not exchanged as per contract.It came back from repairs and found at home that it is still faulty.Go back and send it another 2 times in. Every time they change the speakers that are not the fault. The phone screen is scratched from all the handling at the repair centre.In the meantime I was at the shop 40 times. \""No response\"" was asking to right an e-mail that they send to Samsung.\""No response\"". I have a contract with Vodacom for 20 years"
