My Dead Phone

I took my phone inn for repairs on the 19/01/2016 for repairs at Foschini Durban Central, I had to go in every week to check if its back fromthe repairs but with no luck. I then went back on the 17/02/2016 and the guy that helped called Vodacom Repair center who that advised that they have not received it. We then had to call courier guys for them to send us the proof that Vodacom received it, it was sent to Vodacom than on the 19/02/2016 I went to collect it I was then told that they can't fix it due to physical damage. Now is it fair that it took them the whole month to tell me that its physical damage. I'm not because it took then two days to courier the phone back to Foschini after they said they cant find it. I dont trust that they even looked at the phone and I don't understand the physical damage because the guy that was helping me told me that not much information was given. This phone was purchased last year June and it wont charge how can I damage the charging point because it closed it has a cap to close it inside. It not visible.
