Unhelpful

I am so frustrated and irate with the whole Situation. I have 2 clothing items which are too small. I was at Edgars the Grove with my slip and they were closed due to loadshedding. So now today like the devil wants it I returned to Edgars to refund and yeah my slip is gone and there is a hole in the bottom of the bag. I then got my transaction details from my FNB app. There it states that I bought for the amount at The Grove on the date with the transaction number. So now, hoe difficult and impossible is it to retrieve my slip on the system on my transaction number? Its like you guys just dont want to help!
