Don't use this bank

I have used citibank twice in the last 8 years. The first they had an IT issue and I couldn't transfer my money out for weeks. I threatened a FINRA complaint and then finally I magically could. The second time years later I signed up for a free checking with a bonus, they didn't send me my 1099INT and it also wasn't available on their website. The website just said "Looks like we’re having a temporary technical issue. Please try again later." I received no useful help when I reached out.
