Disgusting service from Vodacom

This is the second complaint about the same phone. After the last post on Hello peter I was advised to book the phone in again for the 7th time for the same problem. I was then to send the job number via email and that they would escalate the problem. This was done on the 21 May2019 and I received confirmation that the email was received. A few days later on the 24 May 2019 we received a sms that said job number ********** 6 has been exchanged and is ready for collection. we collected the phone and when we got home and put the phone back together the phone was still the same and her emails and photos were still open on the phone. The phone has not been fixed or exchanged as the message said. I sent another email to the person who said they would escalate the complaint and asked them to call me urgently. This was done on the 24 May and as yet no response. This is really the worst service I have ever experienced and would not recommend to anyone to take out a contract with Vodacom as you service is really ****. I was asked to rate the service I received. I gave a zero rating and was called by a gentleman a day or two after this. He promised to look into the case and call me back the next day. That never happened. I am paying a lot of money for a phone that cannot be used. I am intending to get legal advise as soon as possible as to how I can cancel these contracts as this contract does not mean a thing to us, as the phone is not able to be used. It appears that the customers are not important to Vodacom.
