Google Business Profile Page Suspended for Google Voice? | Help & Support for Google Local

We have a service area based listing on Google maps for our carpet cleaning company. I used the free google voice number associated with our non premium gmail on the profile. We cold called a few businesses and within days were suspended by a non-human due to not following use guidelines. We reached out and it was overturned. We did not use the number to cold call anymore but did use it to go back and forth with potential customers via calls and texts. A few days later we were suspended again for not following guidelines with no reason why. My questions is: If I pay for a premium google voice number will this help us stay within guidelines? Please let me know the best way to approach. I cant really afford getting a dedicated number from a major carrier yet.

second suspension.
I did not change the Google Voice number but refrained from using the number for more than contacting existing customers I had been in contact with.

I had to login to my profile it did not email me.
