VODACOM - THE WORST MOBILE NETWORK CUSTOMER CARE AND SERVICE CENTER

I have taken my husband's Samsung J7 Pro in to Vodacom 4U Hillcrest to repair more than 5 times for the same problem. We have requested a swap out phone but have been declined as the contract still has about 9 months to go. The final straw happened this week.... I collected the phone from the store after they had it for about 4 weeks on Monday 20 May 2019. The phone was not used at all or even turned on until we took to Samsung at PAVILION on Sunday, 26 May to get a screen guard and protective cover. We discovered that despite VODACOM repairs having the phone for ages the screen wouldn't turn on. So we took it back, on Sunday, 26 May 2019, to Vodacom 4U Hillcrest again. We signed all the forms including the insurance forms. They sent it to the repair center on Monday morning WITHOUT the Vodacom insurance forms that we had signed. The repair center called yesterday to inform us that they never repaired it the time before as they didn't get the insurance documents and just returned it to the store, which I wasn't told when I collected the phone. They went on to say that the same thing has had happened again and they are returning it to the store without repairing until they get all the correct paperwork. My husband has now been without a phone for over 5 weeks. I have repeatedly left messages for the VODACOM 4U HILLCREST manager to call me to no avail. I am beyond frustrated. I continue to be charged the debit order for a device we do not have. Both my husband and I have been with Vodacom for more that 20 years, but will be moving to another mobile network supplier the minute this contract expires.
