Poor network coverage

[Lawrenr]

I have poor coverage at home and I have tested 2 other locations within 2 miles of home on many occasions, with 3 different phone models . All locations are listed on the 3 coverage checker as excellent for 4g. Coverage is in fact non existent- you can’t make a phone call or a basic data operation like fetching an email. When I raised this with 3 they said the coverage is excellent because the coverage checker says so!! Does any authority check 3s claims or can 3 just lie about coverage with impunity?

Only place I have any bars is on the loo

The networks work on postcode are and not individual addresses. If you use the OFCOM checker they go down to the individual postal address. I checked various addresses in my postcode and mine was only 3g while others were 4g and 3 gave me a decent discount for the duration of my contract as they could not guarantee getting 4g to my property.

OFCOM make their API available for free but 3 choose not to use it. Why not?
