Very dissapointing customer service

So dissappinted with Nedbank After submitting twice at Durbanville branch I was called again by Nedbank agent the name of Miriam Phiri requesting that I submit my valid Visa/permit which i did on fhe 28th Novwmber 2025 She acknowledged via emailed by saying that my data was received, uploaded and updated only to found out after a month that my account is blocked the card is restricted. Went to the Durbanville branch again where I was told that it is best to contact Miriam Phiri since she is the one who loaded the document but I have sent emails and she is not responding. Then they gave another email address where I can log a complaint since this morning it is only automated reply amd just now I received an sms saying it will take 21 working days for them to help me.

I wonder if it's because I am a foreigner that I can be treated anyhow and no one cares.
