3 Replacements of iPhone 7 Screen since August and it still doesn't work!

My screen on my iPhone 7 has been giving me problems since August. I have taken it in three times already since my first screen replacement in August:- 1) I cracked my screen, got it replaced ---- this was the beginning of my problems. - replaced screen at Mall of Africa. 2) Screen Dim Sensor wasn't working, so every time I called or someone called me,the screen would stay on and wouldn't go off. - replaced screen at East Gate Mall. 3) My touch Button (main button on iPhone) stopped working & screen went blank. - replaced screen at Mall of Africa 4) This is the fourth time that my screen is NOT WORKING!! I cannot do anything on my phone. I get messages and calls but the screen wont work, it just doesn't detect touch. This has been going on since 28 October 2017. I am using my phone for Business purposes, I think that I should be compensated for all sales that has been lost as well as petrol for the unnecessary distances that I have been making because there is no 'We Fix' shop near Kempton Park!! I have now Queried for a new screen and have been told the waiting period is 7 working days. This is unacceptable!!! This is my First iPhone that I got in December and I am extremely disappointed in the the amount of times I have to get a screen fixed in the short period of time. Very unhappy, unsatisfied, disappointed customer!!! Chris Basson ********** **********
