Multiband - Fargo

My mother moved into Silver Creek Assisted Living (Olive Branch MS)  in March and we got her set up with Directv -we were told we  HAD to go through Multiband for installation.  NO one explained that there would be a $7.48 "protection plan" fee every month charged by Multiband to her credit card every month.  My mother moved out in March - she lasted less than a couple of weeks there - we cancelled Directv and mailed back the equipment.  NO ONE TOLD US WE HAD TO NOTIFY MULTIBAND.  I found out beginning of September that my 82 yr mother has been paying this $7.48 charge every month for 5 months.  Would not have known this except Silver Creek forwarded a bunch of mail to us recently that had these invoices.  Obviously my mother has not been checking her credit card statement which is another issue.
I wonder if Multiband has been double billing this same apartment - its current tenants and my mother who left in March.  Don't know this but wouldn't be surprised. 
Do not recommend these folks at all.
