Want my money R1247.

So it happened I went to Woolworths at The Glen mall bought items that costed R1247 as I finished paying using my card electricity went i was told my transaction didn't go through so I can not take the goods with me but on my account money was deducted already I showed the proof to the store managers but they couldn't hear me out I eventually left hoping to get back my money in 48 hrs but that never happened till today 14 days later still no reversed money to my account, went to the store several times was told to bring proof of payment I did but still not a word from Woolworths The Glen what a poor service and inconvenience.
