Same thing happened to me.  I’ve been a Quickbooks customer for over 20 years and a Merchant account holder for atleast the last 5 years with zero chargebacks.  Earlier this month I couldn’t process credit transactions with Go Payment. I called QB support and they said my account was closed with the explanation it was a business decision.  I asked for more info and they said there was none. They said I had to reapply for a new account in 30 days.  I tried to get to higher management, they said there was no one but maybe the credit card fraud hotline.  I called them and they told me the same thing except they would initiate an investigation and I should hear back within 2 days. 5 days passed and nothing.  I spend over $200 a month on QB and this is the service I get.  Absolutely infuriating.  I’ve been needing a strong enough motivation to leave the platform and it seems to be the final blow to me.
