My ISP is Iberbanda and I have a 1Mbps wireless internet access contract with them.
I have been suffering a slowdown with my internet speed and did a check using - http://www.testdevelocidad.es/

The results showed that I was only getting, on average, .5 Mbps speed. (Point 5)

I contacted Iberbanda and they state, 'The velocity test results that you send to us are over the guaranteed (10% minimum velocity in contract)'

I take this as meaning that if i received just .1Mbps (Point 1) speed then this is ok.

I cannot believe that this could be right.

Is there an Spanish Internet Onbudsman office that I could complain to?
