I admit and I suppose its no surprise for any of you, but I am pretty stupid.
I was being charge since November 2017 and extra 25-30 euros per month by Vodafone, and I just found out.
First 2 calls, the guys would say its something you bought/used with your cellphone and its a third party. They could not give me the name of the third party, but they would give me back the last month and block those charges.
It was a total of $230 euros so I kept insisting and finally one girl called me back to tell me it was a mistake on the system and she apologized.
Sadly, I am not able to get my $230 euros back but I can only get it as credit into my account. I suppose this is the best I can get.
