Cancelled order even tho payment was made and lack of communication

I purchased 2 items on the 19 March 2021 via the online South African store for adidas. I paid via eft and send the necessary proof of payment. Today the 22 March 2021 my order has been cancelled even tho I’ve sent proof of payment and contacted the bank to make sure the money has been deducted from my account. I’ve tried contacting adidas via email and telephone with no response especially via email which is frustrating could someone please assist me as this is terrible especially from a well established company like adidas
