Bad / No connectivity

We've raised this issue before, and although numerous promises have been made, we continue to have connectivity problems in our area. It seems far worse when it is warm, and have really struggled in the last few weeks. Calls are either interrupted or dropped, getting on to the network is an absolute nightmare and can take many attempts. My phone often shows GPRS or EDGE and rarely connects to 3g.<br> Today, I can send emails, but can't receive... What's up?<br> Please check our tower - again - and give us a firm commitment to actually doing something about improving the signal in our area. If I need a booster aerial, then kindly provide one. Surely I can't be expected to pay my monthly subscriptions for mobile and data and all I get is continued frustration!
