There’s away around the blocking, it will take a few months and you pay the interest etc. people still disappear especially in rural areas. I was getting a 50,000 bonus two years ago a month away, I bought roughly 30,000 for home improvement on two cards almost complete maxed them out and then paid them off once they bonus cleared my bank. Never once did they stop the purchases and they collected zero interest. More would take more time, with a large and long credit history they have never fucked with me.
