Disgusting customer service

Cellphone was sent in for repairs. I called 1 week later to check if everything was ok, i was told my phone will be ready for collection by COB. on arrival i was told it was not ready and that i should wait 30 minutes. After 30 minutes i was told to come back the following day at 10am. On arrival i was told my phone was still not ready. I waited 5 hours!!!!!! and when i asked for the manager, he shouted at me and asked me who told me to come in and did i receive an sms. I told him his staff had told me to come in, he then shouted at me again saying that if i did not receive an sms then i should not have come to the store.

I told him i had missed 2 appointments because of this issue, he did not care and said it was not his problem and that the lady who was assisting me would pay me for the missed appointments from her salary at the end of the month. I declined to take money from her as this was not her fault.

Now 1 month later, i open my selfie camera to find there is dirt under the screen that blocks the camera.

I am being told i must find my receipt and take my phone in again, and i have to wait for my phone to be repaired again.

This is disgusting customer service.

How will this be rectified?????????
