Woolworths lost my R42,000.00 payment!

Woolworths financial services, credit card division has lost my payment of R42,000.00 which was paid on the 2 June 20. It is now the 17th of June and no one has contacted me even though I have phoned and sent mails as instructed multiple times. How can a credit card service provider lose a payment? R 42,000 is a large sum. Where is my payment? Can someone from Woolworths resolve this issue? I surely hope I don't get charged interest over this time. It is time to close this account. Surprisingly, very bad service.
