Hello sir,
A word about negative reviews:
1..Negative reviews / Fake reviews from GOOGLE BUSINESS PAGE can not be removed by HACKING.
2. They need to be addressed properly and resolve the grievance of the customer.
3. If it is complete fake review then the same can be reported/flagged AND addressed.
I can do the same for you and can get the negative reviews resolved or addressed at least.
Contact me once so that we can discuss more and get the work done.
