Double payment

On the 22nd of December, I picked up a discrepancy on my bank statement. For a bill on the 29 November for around R313, R600 was swiped off my card. I called customer service and went to Silver Mountain Spur in Blue Route as advised. I spoke to the manager, emailed him my statement and contact details and have since heard nothing back. The waitress was still there working? Two weeks later...No apologies. No feedback. Wonder how many other patrons mislook this and if Spur has anything in place to pick up a tip of a 100%!!!
