Pathetic service at WeFix Cavendish

I took my mobile phone for repairs to WeFix at Cavendish on the 7 March 2018. I was informed by the assistant that I would get a response regarding what the fault with the phone was within 2-3 working days. She also advised that if any parts needed to be ordered,it will take approximately 2 weeks. She assured me that I would get regular notifications updating me on the fault on the phone as well as quotation for repairs.She advised that repairs will only proceed once I have provided approval for the repairs. A week later when I did not receive feedback,I called WeFix .I was informed that the technician was off sick and therefore there was a backlog. I was advised by Nadia that I will be contacted regarding the fault shortly. When I did not get any feedback,I decided to pop in to WeFix to find out about the status f my phone. I was then informed that the Technician tried to call me that morning to inform me that when he tried opening the back glass cover,there was "apparently" a hairline crack which proceeded to become a series of cracks which was now clearly visible so he needed my approval to continue. I found it strange as I was not advised when I handed the phone in that there was a hairline crack on my phone which could worsen if the phone was being assessed. In any event,the technician advised that the fault was probably the battery which would cost approximately R600 to replace.He advised that the back glass cover which had cracked would cost R900.00. I informed him to only replace the battery. A week later,I called WeFix to inquire as to the status of my phone. I was then told by the assistant that it was ready for collection,but she will just confirm and get back to me. She called and informed me that the technician wanted to speak to me. The technician then informed me that it was not the battery,but he had now diagnosed that the fault was on the motherboard. I was confused as to why the correct diagnosis was not made initially and I informed him that I would collect my phone . WeFix claims to provide fast and efficient service but my experience has been that the service at WeFix Cavendish is extremely poor and I will not recommend anyone to take their mobile phone to WeFix Cavendish for repairs .
