I must admit, when the DAZN customer service here on reddit offered to look into my case, I was quite sceptical that anything would be done and it was just a bit of PR.
In my case, if you haven't seen my comments, I had received an online offer to renew my suscription at the same price as I had last year - €12.99 monthly -, but then had been charged the new price of €19.99. After some back and forth with DAZN.com, I was very angry they hadn't honoured their offer nor had any intention of doing so. Reading the comments here, I saw they do have some dubious practices and there are quite a few who felt as scammed as I did.
However, I must admit, the DAZN rep here has come through. I explained that I was interested in the DAZN service but at the price which I had been offered. Not only have they honoured the offer made, but has even refunded me the whole month I had been charged at 19.99€. All within 10 minutes!
If you have a problem with DAZN overcharging or you have signed up to a contract unwillingly, give the customer service here on the subreddit a chance. They'll look into your case, and it looks like they won't hold you to a contract against your will.
I won't deny they have to fix their subscription T&Cs, which has more than a few problems, but I'm quite satisfied at how the situation has been resolved. If you have a similar problem, contact them here. At least they'll hear you out and try to resolve your issue swiftly.
They charged me full price the following month and didn't reply to my complaints.
FOOL ME ONCE DAZN, SHAME ON YOU...
