No Real Repairs Here ... just broken phones and headaches

I took my phone for a glass repair both front and back covers ended up being replaced (they told me the back was buckled). After the repair my one microphone on my iPhone no longer worked. I have been back 5 times to have it repaired and in the interim lived with the sound issues for months. Each time they have a new reason it’s not working. I needed to reinstall WhatsApp but it wasn’t just not working in the program, it just had dust, it’s a known issue (neither Google or Apple agree or have this issue anywhere online), the technition that worked on your phone isn’t working today... and my favorite you need to take it to our head office for a senior technician to work on it but they are closed right now (Saturday)... oh and Then they preceded to include me on a whole host of internal emails unintentionally...have we quoted for the Repair, we will need days to assess the damage... when I made it known I was on the emails they proceeded to ignore me... no email no call as I had asked for them to resolve... crickets!! Seems they don’t take responsibility when their junior technicians (that run stores) make mistakes.
