Google has suspended your page due to quality issues.
guessing your guess is wrong.
The main reason for the suspension might be the address - its notorious for virtual office spam.
Are you able to give the proof the business exist in its own brick and mortar office at this address - then there will be a possiblity to help you.
Attention: Google decided in their fathomless wisdom changing in March 2017 their system of notifications about new threads or responses in the GMB forum to a very worst behavior. This way they corrupted my workflow entirely. Don't expect I will notified about any new response by you on my posting here unless you're using the mentioning functionality on your new response - mentioning me per " @[my name]"
