Then, use other financial services platform that receive bitcoin. Maybe, you can't directly transfer it to those that's why you're having a hard time. I use https://coins.ph here in the Philippines and from there I can transfer my payouts to bank accounts, debit card and even paypal. I'm not sure about what your country use, though.

I also had a problem with my registration in coins.ph before. I just sent them a proper email of inquiry on why was my identification invalidated and what should I do about it. Talk to them first. Calmly. What if they have to validate your information in 5-working-days first? Or what if you sent them an unclear ID? Ask them. If it's still not working, then look for other platforms. You didn't really pay for the registration, right? You just submitted IDs.

If you wanna cash out, you can google tutorials. Just be resourceful. Here are some examples:
