Unfair treatment

On the 6th October I was instructed by Dial Direct to collect a hired vehicle to Europcar because I never received any communication to return it, Europcar sent people to collect it while knowing that my own car is still with the panel workshop, Dial direct failed to inform me about this whole issue and now I was treated like a ******** next to my family. I had to extend the days till 21st October out of my own pocket and when I log the compliant they inform me that they will come back to me on 27th October, Now I did ask them what will I be driving between then and received no answer. They are asking me did I contacted the workshop regarding my car and told them its not my responsibility to do that they are the one who sent me to them.
