Poor Customer Service

A claim was authorized by Insurance to get my vehicle repaired. I called Renew-it Randurg on the same day to book the vehicle for repair, they advised that they do not have the parts that need to be replaced on my vehicle, they need to order them from Germany, which it will take about a month for the parts to be available. I followed up on the status of the parts on 25th April, they told me the parts arrived on the 21st of April, however, they are still missing one other part, it took me contacting me about the status of the parts they claimed not to have. I have been calling since then to find out when the outstanding part will be available and when my vehicle will be booked in for repair, no one is giving me answers, they keep saying they call me back, and they never call me back. I am super frustrated, very very disappointed at their poor customer.
