They only gave me the contracted speed for 2 months, after a whole ordeal, for 2 months of the 1000 mb contracted sometimes they do not reach 300 mb, you measure the speed in a period of 2 hours and it is never constant reaching down to 30 mb. I have more than 25 calls, each of them give you different answers, it is seen that they do not form them properly.
