Quick Quack Car Wash - Klein Louetta

My wife and I really enjoyed Quick Quack, however, we signed up for multi car membership and were told it was $20 for the first car and $10 for the second but a few bills in the cost went from $30 to $45 with no notice or anything. Lucky we we checking out bank acct and my wife noticed the increase and when we called their response was we must have gotten an introductory rate, which is fine but would have been nice if someone would have explained that to us at the time we signed up, so unfortunately we had to quit the service as $45 a month is a bit much for us.
