I also encounter same issue. I do transaction like normal, just I have more than 5 credit cards saved in my wallet. You also save a lot of credit cards insides? You just give them a call only then resolve immediately?

So, u login to multiple devices for ur tng eWallet acc + u use the same credit card in different tng eWallet acc?

This is consider violation of their tnc.. many eWallet is having the similar measure to reduce fraud case..

For my case, they closed case without asking for any details as I didn’t violate their tnc but they suspect I violate.. I believe is bcoz there is once I change to another phone to login as iOS is down.. n I was at the restaurant which come with tng voucher discount if I paid with tng eWallet.. that’s only once.. then they soft ban me after few months of the login.. n they didn’t tell me whether this is the root cause.. just unbanned n close case n suddenly can reload with credit card without issue..
