Very poor service and speaks lies

I sent my Samsung S5 which is just over a year old for repairs on 26 August 2015. On 23 September 2015 , I receive a call from them informing me that my phone is ready . I went to collect and found that nothing was done to my phone after 1 month. I called the manager / owner called Devan and he promised to resolve and call me back. Since then , I have made more than 20 calls to their various sections and everyone keeps on giving me a different story. The just keep on lying to me. I was promised a loan phone and it has still not materialized. Very dissapointed with their attitude and service.
