No service provided

I registered a windscreen claim on the Miway app. It was approved, I got email confirmation that the claim has been handed over to a service provider to replace my windscreen, and that the service provider would contact me. A week passes without a call. I contact the service provider they say my claim is not on their system. I call Miway to find out what the issue is. The agent assures me that they have re-processed my claim while I’m on the call and that this time everything is going to be sorted. Another week goes by , and no call from the service provider. I call the service provider again today and my claim is still not with them. I’m at my wits end with this lack of service from Miway.
