Manager refuses Refund

<p>Ate at this restaurant and my card went through twice. After 7 calls, emailing the manager, sending bank statements and even having the waiter admit the machine was faulted and showed up twice on cashup... no refund or atleast deduction from next visit was given. The hostess, a young girl, was trying her best to assist me but the manager was both times busy drinking with his friends and wouldnt see me. She just gave me a business card and said to come again. </p>
