Toyota Worst Service Ever

On the 30th of March my wife dropped of my car for service at Toyota Strydom Park. Booking in my car was Sanjay of whom I explained to that I took an extension on my Service Plan the reason I made him aware of this was that on my 130k's service I experienced delays in fetching my car because they processed it not from Innovations Group account but the normal plan. On fetching the vehicle I was told it us cash payment of R2248.72. I didn't budget on that since I knew I was covered by my extended service plan. On explaining to Kaz, the manager, I was told he couldn't do anything since there was digging at the premises and power cut. Kaz said theree is nothing he can do since he can't confirm, I tried in vein to explain but it fell on deaf ears. The roller doors to the premises where then rolled down indicating that my car was going to be locked in until they fix their mess. I then requested for a friend to borrow me money to pay since I needed the car to take my kids to school. I felt that I was treated very unfairly and at the end I was the one to do follow ups. The matter was looked into after several calls to the business and a check which to date has cleared was sent to me.
