Terrible terrible service

My story is very long but to put it in a nutshell , I purchased 2 items on my account - got hone out the packet in my wardrobe and put the folded slip with my accounts slips after a week I thought twice about the one item and went to return it forgetting the slip / got to the store - they couldn’t find it on their system - went another branch got hone , got the slip only to discover it was charged to someone else’s account ! I was upset for the other person went back to the 1st branch I originally went to and explained they told me to leave the tshirt there as the other account had been blocked , I said no ! I need to sort this out Phoned the call centre no help - finally got a very helpful manager who promised to get the area manager for Truworths Clearwater to phone me - I’m still waiting for the call went in again on Sunday to Truworths - Clearwater asked for the manager - not available - Rude staff member / went I. Today same branch after work Rude staff again ,and once again leave the item I said no - phoned the call centre to speak to a manager not available REALLY TRUWORTHS , I’m an honest person trying to sort out a problem and I’m treated rudely , and I’m running from pillar to post .PLEASE CAN SOMEONE CALL ME !!!!!
