Signed on for a trial. Have been billed since 2015, twice a year. Very little data, poor search engine, NO CUSTOMER response. Did not catch the twice yearly billing, ok shame on me, did not catch it until this year. Hidden in all the other card bills. Hard time cancelling, non-responsive phone number, questionable e-mail response...
These people sit back and rely on consumer mistakes and billing oversight / lack of close scrutiny to make a good living...
