Mica Hardware's zero customer service

I am sharing this email on this platform on 30 October 2020 and there's still no response from the Mica Hardware.

Dear Sir/Madam

Your customer service is appalling to say the least. On Sunday (6 September 2020), I bought a 4 step ladder for R689 at Mica Three Rivers which was on special for R499. Upon realising the error of what had happened I then returned to said store on Saturday (12 September 2020) to get a refund on my purchase as I was overcharged for it. The lady at the store told me that the manager would decide on whether I get my refund or not and that they are the only ones who can administer a refund, this is after I had furnished her with all the necessary documentation, store catalogue and slip, to support my claim of being overcharged. The store lady got back to me on Monday (14 September 2020) the lady at the store called me back to tell me that the store manager had granted my refund and that I should come to the store on the very same day to which I objected and had to explain to her again that I am a shift worker and could not collect the refund on this Monday. I told her I would collect it whenever I was in the vicinity because I am quite busy to keep going back and forth to the store for the same thing over. She said that she would talk to the store manager and see how they could help me out, I am still awaiting her feedback to this day (22 September 2020). Last week Wednesday (16 September 2020) I called Mica Head Office I was put through to Sheila to help me with my customer query. I explained everything that had transpired up to that point to Sheila and she promised to sort my problem out by tomorrow (17 September 2020), that I would be a happy customer. I write this email today (22 September 2020) neither has the lady from the store nor Sheila from head office returned to me with any sort of feedback on the way forward on my matter. This was my very first purchase at Mica, which I explained to Sheila, and seemingly last by your level customer satisfaction if you can call it that.

I am particularly interested in my full refund. Is there anybody from Mica who can help me with that?
