Broken bumper, no follow up from discovery

My car had a cracked bumper which was repaired by Super Body, a service provider discovery had booked to do the repair. I collected my car beginning of the month in June and 2 days later the front fender or bumper cover broke, it was not properly clamped. I logged a call with discovery regarding this and they would log a call for me to with the service provider or I can go. Which I went to the place, they assessed the car and figured they needed to order a new part. Not even once did discovery check in to find out if this was sorted yet I continue to pay my premiums with no hassle and I paid excess fee which was required of me for a job half done. It’s been over 3 weeks since their service provider said they would order a new part and no follow-up from discovery. This whole thing is such an inconvenience, I pay for a service but not get 100% satisfactory results! This is unacceptable from both the service provider and insurance.
