So last year I signed up to Wolfram Alpha Pro with with an introductory offer of 3 months extra free.
That was on 30 April 2015.
Renewal date was set at 30 July 2016. All's good, that includes my 3 free months.
This year my subscription is renewed with the annual fee of $65.88 on 30 July 2016. OK, that is including the 3 months free.
However, the next renewal date is 30 April 2017!
That is 9 months for a 1 year subscription fee!!
So last year they gave me 3 months and this year they take the 3 months back!
That is NOT 3 months free, is it!
Shame on you Wolfram Alpha!
