Fix this or I am out of using fnb for the rest of my life

I went out to have a drink tonight using my debit card, and they f!?! Deactivated it with out my consent And I was stuck at this far away from home and couldn't go home because they deactivated it, I am up to my head furious with what they did then i call the custom line and they keep on changing it from one person to another and different story all the time and they couldn't help me at all, I even tried to get my dad to help me and he could do nothing for me. Now I had enough. Ether they reactivate my card and pay for person trauma or I go use one of the other banks.

I've been a custom for 13 years and they treat me like this, if I get a reply saying I most phone one of they customer care or anything else I am going to lose it.

If they don't make it right i am going to tell everyone how I now who uses them t switch to another bank, that is about 1200 people
