CelltechZA ******, ***** parts (Apple products) and don’t fix devices

I took a watch to devices to be fixed by CelltechZA, each time they gave me an excuse as to how my device can not be fixed. I mean it was just a screen replacement but each time my device came back not being able to switch on. I suspect that they ***** parts. Guys be careful, especially black people. They don’t give us good service and they take long to bring back our devices. I know other people that had similar experiences. My Items, where Apple products. What a waste of my time and money.
