Poor service at Joe Soap Car Wash Canal Walk

I dropped my car off at 3pm, spent time at the mall and collected my vehicle at 8pm. I paid over R400 for the car wash. This morning I noticed my wheels were not cleaned fully and found more pots where the vehicle was not fully cleaned. This is nonsense service and I would like compensation as I will need to pay another car wash to finish the job your staff didnt do.
