I'd call their customer service line before that. I have always found Thai banks very helpful and often better informed/more capable than the branch staff.
Mild BPH. It doesn't treat the cause but relieves the symptoms, I was prescribed it by my GP in the UK 2 years ago and it has been effective, and my condition has remained stable.
I had the same with my Kasikorn card. Couldn't use it online. But I had to register with "verified by Visa". Having done that no problems. Maybe a similar issue.
I answered this in an earlier question. I don't care if it's legal, or if they are reputable, but it works. At least the side effects are the same as the stuff I used to get from the UK NHS. I take it for prostate, but get the side effect benefits that others take it for.

I stayed there for over a year and it was fine as I had a car and motorbike, it was in the days before Grab, Bolt, etc. In those days the only local transport was a baht bus along Nernplubwan to Sukhumvit, even motorbike taxis were few and far between.
