Worst Customer Service I have ever Experienced

I am really unsatisfied with We Buy Furniture. I placed a laybye with the Montana branch on the 21st November 2020 and paid the required deposit. I then paid off the balance and sent proof of payment on the 17th December 2020. I also called the branch on the 18/12/2020 and asked when stock will be available for collection, then i was informed that the laybye was never loaded and that they are getting someone to work on it, all this time i was the one who kept on calling in to follow up on the latest update, the store never called me back to gibe me any feedback. Yesterday I was then referred to the laybye department to check for myself what is happening, I was given a contact number where i can reach the lady working with laybyes. The lady checked for my proof of payment and said she is sending it to stock, I never got feedback from her. I called the later numerous times and texted on whatsapp today the 22/12/2020 and nothing. I called the branch and asked for a manager, the guy who picked up said he could help and referred me still to the laybye department, even after i told him that no one is taking accountability for my query and no one to actually give me an answer. I called back head office, my number was taken and still to this time 15:38 I haven't received feedback. Im asking myself now, who to actually forward my query and complaint to? it just seems like a dead end, which ever way i try to get answers seems to fail. I just want my cashback.
