I have just had a call from a call centre (Indian accent) asking me to install an App which would give the 'Virgin Media' person on the phone remote access to my router. I have seen this done in scamming videos, very pushy person, kept insisting on continuing, despite me voicing my concerns about security. I was passed to 3 different people during that call (incl 2 managers) Apparently my wifi speed is not good and they needed remote access to fix it, as lockdown is preventing engineers from getting into customers' homes. Scam?
