Horrible online store expereince

on 29 November 2019, I bough a few items on the Clicks online store, after I had paid for these items I did not receive confirmation of payment from Clicks, so I called the following day (Saturday) to find out why I had not received confirmation, I was given a reference number and was advised to call on Monday as that's when the finance dept will be around. I called on Monday and was told that the online shopping person (Oscar) would contact me before the end of business, I never received correspondence from Oscar until the following day, when he asked for my bank statement, which I sent the same day, as they could not locate the amount I had paid. I sent a follow-up email asking for an update form Oscar the following day and the day after. I Decided to call on Friday and requested a refund, i was told that Oscar will contact me before the end of business, which he did not. On Monday, 09 December 2019, I called again and got the same response. 10 December 2019, i got an email form Oscar asking for my banking details for the refund and he told me that the refund will take 14 - 17 days to reflect on my account. Today is the 27th of January 2020, I have yet to receive my refund from Clicks, I have been calling and sending emails everyday since the 13th of January but I still receive the same response of "Oscar will get back to you before the end of the day". This is annoying, and is very frustrating as I have been waiting for my refund since last year, Oscar has not responded to any of my emails nor has he even tried to get in contact with me. I have received such ********** service from the online shopping department from Clicks.
