Non- Existent American Express Service

On the 11th January 2022 I app**** for an American Express card and was provisionally approved for a certain amount pending me sending my ID which I promptly did. I sms'd several times saying they don't have enough information. I tried to phone but they couldn't find my application. Somebody then phoned and confirmed my data and I resubmitted my ID. several times I received SMS's saying my data is incomplete but when you phone nobody can find my application. Eventually I gave up and also received an SMS saying it was declined. Out of nowhere on the 26th of Jan I receive a SMS saying it's approved for a far lesser amount I just need to AGIAN submit bank statements, which again I did. And since then I have not been able to get any information. This is non-existent customer service and Nedbank / American Express should be absolutely ashamed!
