Still waiting for an update for over 2 months

I sent in my phone for repairs and paid for the quote and was never informed or kept in the loop by anyone from the service centre. I had to call them always and when you get a hold of them they never give you a straight answer,now they sent another new quote after i paid for the 1st one. It has been over 2 months and im still getting the runaround from the service centre to the call centre. My reference Number is ***. My service centre reference number is JOB NO: SE122282. At this point im fed up, i just want my phone to be fixed with the original quote i received and paid for.
