Avis Budget Group Budget auto rental tried to charge $218 for a "jump start" that was not requested and did not happen. Washington District of Columbia

Received a letter (see attached) from Budget claiming that I am responsible for a $218 "jump start" that was requested during my rental. Phone call to Budget (case #47489068) revealed that they could not point to any record of my account that showed such a request or an actual service call.

On a completely separate issue during the same rental agreement, I had deliberately declined any 

Rental Options: $0.00 Protections/Coverages: $0.00

but found that they decided to charge me for

Loss Damage Waiver: 30.99
Optional Services Total: 123.96

I was able to get this charge reversed during my phone call but, with the two of these spurious charges hitting me for the same rental, I don't feel very generous to Avis/Budget right now.
