Being bul**** by Support at PC Link Computers

I placed an order for a product that was listed on their website (order #26880) in November 2021. After a long wait, I was told by their support that the supplier was going to take time to do the delivery which would only happen in the last week of January 2022. I waited till then but the delivery was not done. I was then told the order was cancelled but no refund was processed. When I checked on the website, the product was still listed but now with a higher price so I thought they could not deliver probably because the supplier was no longer able to supply at the old price. I asked if I could still order the stuff and pay for the difference but I did not get any response from their support. After not getting any response to my several emails, I then requested for a refund of the money I paid on the original order (order #26880) and sent them my banking details, but no refund was done up to now. I have been emailing *** and *** for the past 2 months without getting any response which I find so rude. Can someone please assist me as I'm sick and tired of being bul**** by whoever has been handling my queries on this order and tell them to stop with their pathetic business practice of not being honest to the customer.
