Unhappy for the service

I was brutally served with very bad service from an Autobody which had me calling my insurance several times and yet till to date my insurance didn't come back to me even so I sent an email notifying them that I'll be contacting hello Peter and still no responce. Car was given to the autobody by the 28th of July to replace the damaged parts as agreed on the quotation and when I went to check the progress on the 1st of August I found them repairing I then asked them they then said " we spoke to your insurance and they agreed to the saver" I then told them I wanted these parts replaced they then said ok. Minutes later after I had left I called G AND J autobody to confirm again if my insurance agreed again yet now story was different then right after they called the assessor to agree with the repairs and not replace so that the insurance could save. That same day I called iwyze claims department and they assured they would come back to me before end of business which they didn't, came Monday which was the 4th of August with no response I called them again and they promised to come back to me, I then called again on the same day and as well as the following day and they didn't come back to me, so I then decided to send an email to their customer care on the 7th with that still I got no response. So my pled is for hello Peter to help me with the matter. Policy number ********** 041
