I've used several Coles Prepaid MasterCards for online purchases without any problem until 2 days ago. I've tried two cards. Both have sufficient fund. One is brand new. One was used in one of the following websites before but is not accepted any more. Here are some websites I am having trouble with now:
PS : The same cards are still accepted in store and on some online platforms, such as PayPal, McDonald's.
I wonder if anyone has had the same experience recently? Any way to fix it ?
Thanks a lot.
