Orange putting my daughter in danger

We bought my daughter a mobile phone from Orange so she could contact us in an emergency.(She is diabetic and also has epilepsy). We were very careful to tell them that it was essential to have as much coverage as possible so the danger to our daughter would be minimised. For 2 weeks everything was fine. The phone seemed to work and apart from the over billing and the problems with the Direct debits being taken out 3 times in one month, at least the phone its self was working.

Then, one night she hikes out of Scarborough with her telescope. To cut a long story short, she fell ill and tried to call for help but the phone had been locked. She was found by a passing motorist the next morning and he drove her to hospital. She is recovered now, but it was touch and go for weeks. We complained to Orange and they said the phone had been locked for non-payment. We checked with the bank and they had once again taken out the direct debit twice in one month, leaving us overdrawn and facing bank charges. They have never apologised and refuse to cancel the contract so we can find a reliable provider. We cannot afford to have 2 mobile phone bills, one of which is unusable. They still owe us 2 months of line rental which they have taken prematurely, and have not paid the bank charges they forced on us.
We are disgusted with this company and want nothing more to do with them. If I could afford a solicitor to get us out of the nightmare contract then I would, but we cannot afford one.
Stay away from this company. They lie and they cheat just to get you to sign up then they don't care about you at all. I told them what had happened to my daughter and they suggested she stay home instead of "gallivanting around the countryside", that made my husband so angry he actually swore at them down the phone!

I don't know if anyone will read this, but if you do then PLEASE stay away from Orange Mobile. They are really horrible people and so rude!
