the network coverage in bradford is so poor i cannot use maps feature or data when in lots of areas

I signed up I'm December since then I've had the worst network coverage I've ever had from any network . The signal for calls and texts works everywhere but unfortunately the data signal is poor in lots of areas . I rely on maps and data fory work and am often out n about and not able to use data I'm having to hunt for public WiFi like a nut just so I can use maps or Internet its ridiculous as I'm paying for unlimited but 95% of the time it doesn't work and never works within my home either . When I speak to 1d they say there data "is not intended for home use "" but this wasn't specified when I purchased.  However since start of contract I've used only 1kb of data which shows how irregularly I'm able to connect . On top of this price of contract went up by over £9 in space of 3 months I signed at£33 in Dec now by March it's gone up to £42 ! To pay South and not be able to use data using disgusting . I feel I was nice in signing up to this network I thought I'd give it a try bur I've been sorely burnt this time abd now I'm stuck with the poor speeds for 2 years !! It wasn't such a good deal as I thought . Do your homework guys
