I've been trying to change my merchant account information for months now. I got a new number and cannot update my new phone number or banking information due to me having to jump through hoops with support. I have even started another case with support 2 WEEKS AGO to change my account phone number on my merchant account, and been having to wait days for email replies. Even then they closed my case twice due to "incorrect documents". It should not be this much of a hassle to change account information, especially when I already changed it on my self employed account, which apparently separate from the merchant account with the same login information. I will definitely be changing accounting softwares after this is resolved!
