Botched my phone

I am so disappointed with cell clinic Nelspruit service. I had a broken screen for my Huawei Y7p this month, this guy fix it but from the moment i left i the phone sensor wasn't working well, i then contacted them to let them know about this. The guy told me to return the phone of which i did, he then said maybe its the screen protector of which i also bought there, he removed it and told me to go home and see if the phone still malfunctions of which i asked are you sure i must go home with this phone like this? It was a friday...the phone still malfunctioned then they told me to bring it back...yhoooo the guy took my phone "fixed it" then gave it back to me with such a bad attitude, he just throw it on the table and left didn't even talk to me, i then noticed it was a lot dull then usually and i tolf him he said to reset my phone...yhooooo guys i left now the phone mulfunctions even worse😭😭 it just switch off the volume at will, then functions on its own without me pressing it, i can't even restart it or switch it off it's very bad...I don't recommend cell clinic in Nelspruit👎👎👎
