Any one else has issues with can stock photo payments? I made withdraw 3 weeks ago and nothing, contacted them one week ago, they answered saying that they will investigate. Contacted again 3 times and no answer anymore.

If they have a problem issuing checks then they shouldn't have them as an option. It is unacceptable to wait several months for payment after requesting it regardless of whether or not it's a check. And it is equally unacceptable that questions about money owed go unanswered. It makes them look unprofessional and like they have no intention of paying.

Keep asking for your money and if you get no result report them to a consumer agency like the BBB or something like that.
