But to change your bank details now, with the troubles with JPA ? The logic is sound but you are more likely to end up without pay than the thousand other "drifters" that haven't been as thoughtful as you !!
Changing bank details on JPA at the present time ? Braver man than me. I'll stick with what details they have and jump on any legal bandwagon when we don't get paid than give them have an excuse that "you must not have saved your details then Sir "
