LIVID, DISAPPOINTED,INCONVENIENCED!!!

I had made a point of purchase in February swiping for movie tickets yet the printer was working but never printed the tickets and now I swiped again on the different machine and money went out. Now I need my first payment to be refunded as I never received receipts but on my bank statement it shows that there was a double deduction. My incident was logged 2_3 weeks ago and nun has been done yet to sort out my issue and I'm now really irritated by their information technology service .its bad very bad
