false advertising

Worst service received with a manager who is unhelpful and sarcastic they offered a free car wash after every ten washes I took my car there regularly and collected almost 30 tickets i then took my car in on a quite Friday morning and was told they only offer free wash Monday to friday by the manager I then left it at that I then got the opportunity this morning to take in my vehicle and was told they do not offer free wash any longer as the have to much problems wit there clients because of this I call this false advertising at least give clients a month notice prior to stopping such a offer as for them to redeem free car wash they will not see me to wash any of my vehicles or to fill up with fuel
