Worst customer support ever

Worst customer support ever. I received an sms that I have exceeded my international limits which is not the case of course. Funny story because I went twice to a branch before I travel abroad to make sure that everything is ok. Not only that, all my online transactions are now declined, can't even call uber. I went to a branch, waited for an hour and the only help was to sent an email which i already have done myself with no reply of course... I am calling the helpline and nobody is picking up. Where exactly is your customer support? Every time I am dealing with you nobody can do anything. From the branch they cannot do it, from the phone they cannot do it, So who can actually do something? And the answer here is going to be we apologize for the inconvenience. Time to switch banks
