sounds like its not getting any data at all.
You say, they installed an outlet where it WAS working fine.. and you have done the other stuff yourself?
The new spot, had the line THERE already? you just put the plate, etc?
I am guessing.. that while there may be other lines running around the house, etc.. that they are not all CONNECTED down at the source.
If you can not figure this part out yourself, you should be able to get rogers out to connect everything properly for this other outlet.
