Non caring response

I took my MI phone to Game Cresta for a cracked screen on 24 August, was told I will get a quote in 2 weeks. At the beginning of the third week I got an SMS that my phone is ready for collection. Excitedly I went to the store to collect, (wondering why I did not get quoted). MY PHONE WAS NICELY WRAPPED and not repaired. Game blamed the supplier and the supplier blamed Game as they said the phone never reached them. A Game staff member called and spoke to Mark at Xiaomi who claimed I was quoted and paid +-R1200 after my quote has expired ( I never got a quote and never paid a cent. At Game they did a 2nd repair slip for me at Mark and Michael's request that they will prioritise my repair. 3 days later when i check with Game I was told the courier did not take my phone because I declined the quote ( how can I decline as I know my phone is out of warranty) The lady Octavia at Game said I must fill in a new (3rd) repair slip and used the words " IT IS OUT OF WARRANTY ANYWAY). If I paid the R1200 mentioned by Mark, why are they not refunding me? Xiaomi and Game Cresta failed me. Honestly, I love MI phone so much.
