Will not release my funds

Square told me I would get deposits within 1-2. I processed a number of payments,no problem.  Then one exceeded $2500 and they asked me to applymfor and increase.  I had more payments exceeding 2000 and NOW after being approved , they still won't release MY funds with no reason. They won't respond to my emails and you can t call.     HELP!!!!!!!!!  I have a small business and have clients who want to via CC and it's easy on the IPad. This is typing up my money andn impacting my ability to conduct business.  How do I reach Square"????????
