EXTREMELY BAD ATTITUDE!!!

On 27 Feb 2015 I went to pay my account in the Vaal Mall Vodacom 4 U store. There was a problem with there card machine so they had to reswipe my card I got 2 notifications on my phone realizing It went through twice, I inform the manager that help me and he reply's in a very rude manner \that is of no use to him I should go to my bank and get a bank statement proofing it"that I can understand... But if this was explained to in a professional manner I would have gladly done that"
