Edgars online's poor customer service

I placed an order online on the 5th May 2020 and till now i have not received my order . When a tracked it online it shows it was canceled but I never received any communication advising me of the cancellation . I have not even been credited my money back as i used a credit card. When I call their customer service number on friday , I held on for 15 minutes without the lady on the other end getting back to me . I eventually disconnected and called back . the gentleman I was speaking to logged a query for me and said they will get back to me . I have still not heard anything from them and when I called today , I was advised to call after 30 minutes as they had system issues . When I called after 2 hours , they pick up and then disconnect my call . This is pathetic unproffessional service .
