Are Mellins in trouble?

I ordered a pair of spectacles on 21 November 2019 from Kleinmond branch, and paid a deposit with my credit card. The receptionists told me I was covered by Discovery, and still took my deposit AFTER Discovery had paid in full. I have still not received my deposit back and it is 28 December. I have been to the branch twice, spoken to someone at Head Office in Bloemfontein and still have received no refund. The same has happened to my husband. He paid in full for more expensive lenses, Mellins told him they could only provide lenses that cost R1000 less, but he has not received the refund! a month later. What is going on? Is this sharp practice? Is this *****? Are they experiencing financial difficulty? It is outrageous. I would strongly advise any potential customer to avoid avoid avoid Mellins i Style. They are also very expensive.
