Horrific service

I took my Car in for service in December 2018 and was assisted by a lady named Ann whereby she promised to call me on the day if there was any problems with my service /warrenty plan.I received a call @ round about 18:00 informing me that I can come an pick up my car as the service had been done and that she would follow up with the warranty plan(window mechanism) and service plan,and she promised to call me back with the details. She called once and then emailed me regardign payment.I paid the invoice and emailed her regarding the disappointment in the servicr I received from Toyota and the problems my sounds my car has making,the loose door handle,and the wires thats hanging out in the car window mechanism and to-date,no response.no invoice ,no information about what has been fixed. I have been receiving bad service from Toyota but this is thus far the worst
