Heddiw, mae Ofcom wedi dirwyo’r darparwr telathrebu, Tismi, am fethu â chymryd camau priodol a chymesur i sicrhau nad oedd rhifau ffôn a ddyrannwyd yn cael eu camddefnyddio, gan gynnwys at ddibenion sgamiau.

Ofcom has today opened an investigation into Xtra Phones, which operates under the trading name Compare The Networks.

Mae Ofcom wedi agor dau ymchwiliad ar wahân i ddarparwyr telathrebu, Vonage Business Limited a Voxbone SA, yn sgil pryderon bod rhifau ffôn sy’n eiddo i’r cwmnïau hynny yn cael eu camddefnyddio, gan gynnwys at ddibenion cyflawni sgamiau.
