******: Charged twice for returned item; No refund after a week; Blames system

I bought a soap dispenser online on a 2for1 promotion which arrived with a thick layer of glue inside. (Order ***). I went to Parow Store to exchange it. It was scanned as a return on invoice ***, along with a couple of other items. I realised after a couple of minutes that I was charged more than expected and returned to the store again. Everyone who looked at the till slip since then insisted that I received my refund as it is indicated as such. Until they use a calculator and add up the totals. I returned all the recently purchased goods and expected to get all the money back that I paid a few minutes earlier (invoice ***). Instead, I received even less than what I paid. The store could not fix or understand anything and referred me to contact the online department. They referred me back to the store. And nobody was willing to quickly solve the problem with a simple voucher. I have waited a week already without any communication form any side. Both sides insist that refunds were processed and should either show up, magically, in my account. Parow said they contacted Head Office to rectify the system. A week later, nothing had been rectified. How long does it take to fix a system that robs people? Isn't that priority? Shame on you MRP. Customers, take note of your till slips. You are being ******.
