@Avon South Africa took my money but never received product 12 feb 2021 up to date

on feb 12th i bought things on line at Avon SA. I payed an amount of R408.00. Up to date i have not received the product, i never recieved any email , sms from them confirming my purchase yet they took my money. I have tried to request my money back till today still nothing. They telling me they want a reference number that I used. where do you get a ref number if they debited the money direct from your credit card it was not an EFT payment. they should be providing me with the reference money not the other way around. I sent the credit card statement they telling me its not enough information, but they can see that on the 12th there was a debit order from Avon Manor for R408.00. They have been sending us from pillar to post with regards this matter its been 3 weeks now.
