I recently did an event to raise money for charity, I needed to supply Strava data as 'proof' - I used the free month service as I didn't have Strava before.
I cancelled the free subscription the day after I took it, so that I wouldn't forget about it and be billed.
I took a screenshot as proof and kept the confirmation email.
I was still billed £54.99! I got in touch with PayPal to dispute it and gave all my proof, but they've refused it.
I worked so hard to raise £135 for a local hospice that looked after my dad as he died, not a lot of money but I really don't have much and nor do my friends/family but I was so proud to raise anything.
This £54.99 is just a huge amount to me.
Beware of Strava! Hope it doesn't happen to anyone else. :(
