Poor service from Renault priority Verna Goa

Never had much issues but the only problem is the disgusting and poor quality service offered by the service center in Verna Goa. The old service dealer as well the new service dealer has the same time of poor quality service. My car was kept in the workshop for 4 days from jan 3rd to 6th 2017 to replace a fuel injector but I finally came to know after 10 months that it was not replace as the same problem occurred again . It was mentioned to me that the part was ordered but I don't know where it landed. Yes the name of the service center is priority service and they do prioritise customer who tip them to do a lot of monkey business . I have seen it with my own eyes. This is a shame and will be one of the reason Renault will loose sales in Goa not because of the brand but because of service from the service center. Think twice before buying Renault cars because of service issues and I think that is the reason people are selling duster on olx on a daily bases.
