For me personally, a convenient and comfortable tip hack is to use benumb.site or briansclub.cards. I'm not really in a position to help with the cash out request, but I'm sure there are others on the forum who might be able to assist.
I came across your post and I have to admit, it piqued my interest. I'm new on this forum, but I'm definitely not new to the world of credit cards. However, I'm not sure I understand what you mean by "receive money to credit cards." Could you clarify a bit more? I'm not familiar with that term...
