After seeing this i got a little worried so just logged in to my account online, not via the app and successfully made my monthly 8,500 transfer to my girlfriend for my house rent.
My account was opened 8 years ago with help from an agent/lawyer when i did not have an address.
I had a message from BB on my account to verify my phone number etc but it only mentioned the mobile banking app so i ignored it, i had left Thailand by then anyway. The message said my account would be restricted by the 29th of April if i did not verify the details.
I am hoping i do not get my account blocked at some point soon but as there is only 70,000 in my BB it is not a big problem, i would just transfer 6 months rent directly from my UK bank to my GF's BB account and sort my account out on my return in December.
If my BB account did get completely shut down, in my situation of only using the ATM to withdraw 20,000 at a time, i would not loose any sleep of being charged B220/£5 to use my UK bank card for the 3 months i am in Thailand. 20,000/£450 a week, £5 a week in charges, it would only cost me approx an extra £65 for my 3 month holiday. It would be higher for the big spenders admittedly but it is peanuts in the overall scheme of things.
