waiting for a repair to find out they destroyed without my consent

I have a problem with vodacom I booked in my phone for repairs in 2016 march I followed up and each time I got a different story about the repair if emailed the Customer care regarding the repair I received a reply that they will follow up this was their reply

Dear Leon We acknowledge the receipt of your email. As discussed today on ********** 854 I tried calling Darren on the number you provided however there phone rang without being answered. I will be trying to get a hold of Darren again during the day in order to get feedback on the repair. Regards, Fundiswa Booi Customer Care eService Team

I also tried following up at the repair center and eventually got hold of Darren he then said to me that he will escalate the repair to his Managers in Cape town an that he will come back to me he took my contact number and till now I didn't receive any feedback I also asked him to please make a note to stop the contract till the matter was resolved as I cant pay for a phone I don't have and can't use as to my matter I didn't received any feedback from Darren. I went to follow up on the repair and I was told that the phone was destroyed and Darren does not work there anymore as I didn't collect it but I was not informed about the repair and now I must pay a amount of R4738 for the phone that was destroyed without my consent HOW CAN YOU PAY SOMETHING YOU DON'T HAVE a speedy response from vodacom will be greatly appreciated regarding my matter The agent at the repair center made a copy of all my emails that If sent to vodacom and emailed it to headoffice and said she will come back to me that was the 27th of December 2018 and still no reply If phoned 28th 29th 30th 31st and still waiting for them to phone me back ********** Jobcard number ********** 9 I don't have the problem paying the amount but how can I pay for something I don't have and asked to put on hold while waiting for the repair
