waiting 8 weeks on a repaired device

I have a Sony Xperia Z2 that I've sent in for repairs on the 8th of April 2015 to an external repair center. It's been 8 weeks since I've sent my phone in for repairs. The shop at Canal walk century city, their phones just ring. Once I called for 30 min continually just to get through and still no answer. On the 24th April 2015 I loaded a complaint on HelloPeter and within the hour the representative (Sanele Buthelezi) from Telkom contacted me. He said he would call within the following day to give me an update I'm still waiting. #telkom this is the worst service I've ever received and I'm ashamed of say I have two contracts with you guys. 8 weeks without any information or updates to date ? <br> My first job Number was Trj001644.<br> The REPAIRED DEVICE TRJ003054 and still no update.<br> <br> They gave me a new phone in the 6th week (20th May 2015)<br> And the screen had a faulty lcd with new IMEI NUMBER. The 21st May the phone was taken to N1 City branch where Fawaaz collected the device. I am extremely unhappy with the service. 8 weeks without a device is pathetic. Honestly I'm so unhappy I wouldn't recommend them to ANYONE.
