Leaving aside the fact that the payment of the bills must be made in advance (I would say that even if you offer me a good monthly service at the end of the month I will pay you, otherwise you will attack yourself, it works like this).
For this type of network it is a theft to spend about 30 a month, slow (even at night), intermittent and unstable (of the series that struggles to upload a 3-minute video). Of course, by means of "ether" one cannot expect better as a power, but I would say that demanding money in advance and moreover the same fee for an optical fiber I would say is a theft.
Ah sure, the "discount" you do it only and exclusively if, by doing 3 tests through their site in less than 8 hours, they are significantly lower values (ridiculous).
Luckily the fiber will soon reach us.
