Club Car Wash Did not provide a service paid for Omaha NE

Recently had My vehicle washed at the 99th st. location in Omaha. I paid for the ELITE was to get the salt off the bottom side.

Once home I put the vehicle on a lift and found the underside had no signs of being washed.

Cutting this short I contacted corporate with no response. After the second contact, They offered a voucher for another wash. 
I said OK but send two so I can try two locations one with my vehicle and the other with my wife's.
This will verify that it was anomaly or equipment issue as they claimed.

No response, No vouchers. It's been almost 3 weeks with not further responses from them.

They are charging for a service not provided.

Many other bad reviews online so it would seem my experience was not an anomaly
Should anything change I will update this review
