Hi Mary Ann,
We are so sorry for the misunderstanding. We looked at your invoices and on your two previous invoices you got the car wash for free due to the promotion we had at the time and on this invoice you were charged for the car wash. We apologize that this was not comunicated to you better. We like to offer you a free Diamond wash for you to use at your convenience with our apologies for this misunderstanding. Please contact me at omid@dowenycarwash.com so I can set that up for you. Thank you for your feedback and we look forward to hearing from you soon.
