Unacceptable customer service

My husband is renting a car from why buy OR Tambo. Car broke down two weeks ago. Have not received it back. After he wrote a review why buy jumped and got the car to Toyota after a whole week. We phoned Toyota the car was done on Tuesday and when he phoned mr Ginesh he said he will advice. Now 2 days later he does not answer any of our calls. This is unacceptable from why buy keeping a customer waiting We pay every month as directed and never late and this is how they treat us. I also work with customers daily and never in my life have I mislead or kept a customer waiting
