Get bothered by this organization about Telfort bills that have not been paid. Because of their threat I have already paid bills that were not even entitled to and guess what ,,,, now half a year later they continue like this. They say that I have to get redress from Telfort and they say everything has been handed over again, we cannot see anything. A THICK 1 for both companies. What a bum first class that this is possible in the Netherlands. Both sides are difficult to reach an hour on hold is quite normal.
