Unfair extra charge

 Hi. Yesterday night I was not even using my phone when I received a message that 80% of my Internet was used up. I turned it off and then in a few minutes I received a message that all my Internet was used up and that I have an extra cost for 35 euros. This is unacceptable. I was not doing anything on my phone and I only have 59 MB usage for multiple times, which is also really shady. From 20:01 until 20:27 I have several slots with 59 MB without even using my phone. I see that this is a recurrent problem with Simyo.
 This is completely unfair and against customer protection policies. You should not treat costumers like this especially because this happened to a lot of people for a lot of times, again for no reason and only with Simyo. The Internet is full of complains still it looks like you are not doing anything to resolve the general issue. This should not be accepted and should not become a recurrent practice. Make better policies and stop making money on the back of faithful customers. Do better! I hope my problem will be resolved and that other people will not encounter this problem anymore.
