Naked because you're barely covered

I have an ongoing claim since early January. I have been messed around with expected dates since the beginning by Technostar, and in April my car was finally given back to me. It was given back with multiple electronic faults which i communicated to Naked. I have communicated several issues I have had with Technostar to Naked. All I get told is that the agent will email the team handling the claim and someone will assist me. Nobody has been of assistance here. I have been chasing down Technostar all on my own at my own cost in airtime. Today I took the car back and was told at about 9:30am that the line manager will get back to me today asap with a booking for an auto electrician to look at the car tomorrow morning. He has not been in touch. I have left messages for both him and the service advisor to call me and they have not.
