[Staffslug] OT - Ad on Panasonic TV

Hi all, Been a lurker here for some time, and intend to attend a meeting in the future, when my daughter is a bit older. Have an OT question that someone may have advice on. Panasonic have a 'feature' called Viera which provides online access to various services. After I updated my Freeview channel information today, every time I power on the TV an ad appears for about 1 second on the bottom of 1/5 of the screen. I was not asked to opt-in to this ad and find it outrageous that Panasonic would take it upon themselves to sell me to advertisers after I have bought their TV! If I unplug the internet connection to the TV the ad does not appear, but I am left with a lessened experience than what I paid for. I have contacted the ASA and Ofcom online. Is there anything else I can do? Contact a politician?? Thanks, Felix
