PSA: check every paid subscription before the end of the year! maybe you don't use them anymore.

I went to cancel two of them although I use them and they gave me 1 and 3 months for free respectively.

make screenshots when you cancel or when you take their free deals! maybe they "forget".

if you call them sometimes they offer better deals, but then there's the danger of upselling and them putting down something you did not choose.
