unsatisfactory support with an incorrect credit card charge

2 UberEats meals were charged to my Nedbank / Amex credit card. 1. I did not order the meals 2. I was out the country when the meals were ordered 3. They did not appear in my UberEast account receipts history

I escalated this with Nedbank's credit card division via my private banker. After a 2 week delay they responded saying that is was not credit card ***** and have not helped further.

I had a 3rd incorrect charge on card to a hotel in Scotland. Despite escalating this to my private banker, I have not yet received a response from the bank.

If I am abroad and use my card they call to verify the authenticity of transactions. I didn't receive any call with regards to the Hotel charge.

Very frustrating to be experiencing this level of service after many years as a client.
