Single platform constant contact Its like malware for your google listing New York Internet

My wife and I run a small company, we recently changed a listing for one location on our google account. Now we we have a another section we can't edit, it lists the wrong phone number, hours and a competitors products. This will do nothing but hurt our business. Bloomnet, Inc, 1-800 Flowers, on our Google page thanks to Single platform. This was not authorized, no one asked us about changing our information, this is damaging a small business and affecting our ability to feed our family. At the least this will coust us time and effort to remove this unautorized harmful link and money in the form of lost sales. It may even effect us for years to come as the contact information, hours open, and products are not accurate, it may damage our rating and reputation. I don't want hire a lawyer but they may leave me no choice.
