No Fault Found !!!

Explained to the Service Advisor that there is a pool of water on floor of the back seat after rains. He asked if I had left the window open and I rep**** no. He said that he could not book my car in as they were fully booked. I explained that this is urgent. He asked that I bring in the car the next day. I explained that I googled the issue and it seems that some pipe/drainage might be clogged. The service advisor chose to not indicate this on the service sheet and said that the experts will investigate. I had to call in for feedback. I called again after 5pm and was told that I should come in for a chat. I was told by the foreman that it seems that the window was either left open or that I was parked in deep water. I asked about my googled investigation and was not given a response. I left without anything being done about the issue. It rained that night again, and the issue re-occurred. I called now for a Repair appointment and can only be accommodated in a week from now. My car is parked out ( as I don't have a garage). <br> Separate issue - I was cut off 5 times by reception when calling in. I asked for the service manager (Karin) to contact me. Until now - nothing !!!!
