Bad service

I took my car for service n they deleted the service history history that is electronicall that was done at BB Nissan were I bought it, wen I return to complain they flatly denied it until I show them the picture of dashboard that I took before I took the car to them. I was told they can only upload it when I can show them the invoice of the service from NISSAN with attitude. Bad service n attitude from the lady at front desk.
