Card Declined for no reason

Sunday, 09 August, 2020 I went to Brooklyn Mall, Pretoria:

• Tried to purchase at Le Creuset – Declined Response Code 1 - Refer to Card Issuer; • Tried to pay for breakfast at Café Frescatti - Declined – Host Response Code: 050; • Card will expire: 03/21; • Credit Balance on my account of R49 929.32 CR – see print screen below;

Please explain and sort this out ASAP since this was embarrassing and humiliated to hear in two places loud “Card Declined”.

Further, kindly note the following: 1. I am not going to a bank for sorting out this problem; 2. You either sort this out ASAP; or 3. Close the account; and 4. Refund the credit balance on the card!
