My membership was frozen, but an employee unfroze it without my request or consent. I was wrongly charged on September 2nd. I went to TMPL on Sept 4th, and asked for a refund. Since then, I have been sending emails to two employees at TMPL asking for my refund. It is now Sept 20th, and no sign of my money. It has been nearly 20 days, three weeks, after the day I was charged, and all I got is "he's inundated with others having the same issue" and "just bear with him". I do NOT recommend this gym because of its customer service.
