If you need any repairs on your iPhone never go to i repair in Sandton city

My phones battery was swelling causing the screen to detach from the phone, I went to I repair in Sandton city they took my phone and said o should collect it in 45 minutes. I collected the phone everything seems to be ok they replaced the battery and glued the screen back in place, I was very happy with the service until I got home and tried to take a selfie! The was glue inside the lense so I thought ok I'll go back and they will fix it. I went back to the store they removed the glue but my front camera lense is damaged and the only way to fix it is to replace it, I asked if I would have to pay for the replacement even though it was their mistake they said yes I asked if it would be at a discount because I didn't put the glue there they did!!! The lady said I'd have to pay the full price to replace it. Now I'm stuck with a front camera that takes misty pictures... i repair is unreliable they fix one problem just to cause a bigger problem so that you keep going back for them to take your money
