Game Cresta Poor Service

I bought a Samsung J5 phone from Game Cresta. It was faulty. I took it in for repairs on the 26/3/2018. ***. After 15 days I went back. It was not ready. After 3 weeks I went back again , still not ready. I went back today . It is now one month. I rather took the liability of buying another phone. It was more a hassle of going up and down.
