No mobile signal

[Angx]

I live in North East Essex and haven't had a good mobile signal for about 10 weeks minimum.  It says it is a problem with the mast - but how long is this going on for.

l phoned sky and was told that someone would get back to me of course this did not happen!
I was told to use wifi calling this sometimes times works but not always. 
l am thinking about changing to another supplier if this is going to be a problem long term.

if you phone sky you get India - and they don't understand the problem and l don't understand what they are saying  they speak to quickly and very fast. 
lve tried all the normal things. Sky is still saying (online) it is a problem with the mast and it is being fixed as they have been saying for months now. 
Any help please

Sky don't own or maintain any mobile phones masts, so you, and others in the area, are waiting on a third party fix. 

Once it's been fixed you could call Sky and request a credit on your account for the time you've had the issue but Sky are under no obligation to agree to that.

Of course changing mobile providers may not help.
