Just thought I'd mention here that I've had three phone calls on my landline today, withheld number, all from someone with an Indian accent claiming to be from Openreach and I'm apparently not getting the speed I should be getting. I didn't fall for it. Watch out for these types of calls.
If I get one more call like it very soon then I think I'll invest in getting a new Truecall device, or something like Truecall anyway.
