Paid for rush service ($270 - 3 service attempts)) to serve a 30 day notice (over a 6 day period…read moregoing into a weekend) to evict persons living in a probate estate home. Server stuck a copy of the notice in the door on second attempt because he "saw rubbish" outside and assumed they had moved. With that inexperienced and stupid attempt he basically told the occupants what he was doing. (I was told by the office that he had 10 years with the company) Three attempts means three attempts, lousy or not. The same night my client heard from a third party in communication with the occupants that they had found the notice (not legal service). I emailed the company THAT NIGHT and told them what had happened. The server had gone out the third time the next morning prior to the company contacting him. The entire time of the contract, it took the office HOURS to contact the server (they told ME this) They gave me one more service attempt because they had admitted they screwed up. The server saw lights on and heard voices inside but (surprise) they wouldn't open the door. For the last three days of the service period, I emailed the company for status without response approximately 10 times. When I called, they told me that they received the emails, and were waiting for their server to respond. I've been practicing law 30 years and have used many companies for service of process. This company had no plan on how you serve an individual, made fatal errors, and had poor communication both internally and with the client. I wouldn't use MSI to serve a notice to a child's teacher that they were sick that day, let alone anything important. Without any doubt among the worst in the Chicago area. Stay away and don't waste your money. ----- Regarding the owner's response below, it is utter nonsense. I sent these guys to serve notice on a vacant house for $270? The owner is lying. I told them three people lived there. They were sent there to serve notice, not to make a judgment call on occupancy? Oh, and do people ever leave a house? Their server left a notice in the door, effectively rendering any future attempts futile. The woman in their office admitted it, that's why they gave me an extra attempt. It wasn't a "courtesy" attemp. They screwed up. You have a weekend job and you don't communicate with the client? That's poor business practice. As far a suggestions. YOU MADE NONE except a stakeout which given your track record would be a waste of time and money.. I emailed 6 times Monday morning for status, and called when you didn't answer. Hey man. I know it's painful to get a bad review. But you should suck it up and try to get better instead of lying on Yelp. You have a poorly run business.
