Hey has anyone been able to get their chica merchant bank account hooked up to wechat pay? If so please advise

You've probably already been into your branch and registered your CMB card/account for online banking but if not you probably need to. Same with CCB.

Mines fine. Linked to wechat, Alipay & Applepay. As nnoble says, go see your bank

Mine is fine as well. If you're not able to set it up, it may be that you haven't set up your account for online banking, or that the name does not quite match what you put in. This is a common problem with non-Chinese names. In Chinese bank systems, they are case-sensitive, and they may or may not have put the spaces in the right place. Double check your online account, or head down to the bank branch for assistance.
