Gearbox guarantee service very bad.

Took ages to repair a gearbox then told lies. Now has a guarantee problem and they have had the car for 5 days . Haven't even looked at it after requesting it in Early on the Monday. Lied again every day and then put down the phone on us.Absolutely disgusting service. Said they would look at it Monday afternoon. Today is Thursday and have lied that they were busy with it every day. It has not even been checked!! Now put the phone down on us .
