Just checked my account and it shows mgm+ at 8.00 per month, but that has red line drawn thru it and shows 0.00 per month. But it doesn't say how long this lasts,...... 1 month, 3 months, forever. I called customer service to get an answer, and they said nothing like that exists. Should I add the offer or not? Already paying them too much, but want to take advantage of something free.
