New Customer - ADT failure to install services!

I signed up to ADT security 10 days ago. Signed the contract and ADT installed their Radio last week Thursday 4th June 2015 when I was at work. Since then I cannot activate my alarm due to a flashing zone light! ADT have already taken their direct debit and since Thursday I have called 3 times, been put on hold for 30 minutes at a time and nothing resolved! ADT allege their engineer report says everything was fine when it was not! I arrived home from work the evening of the 04/06/2015, tested and could not arm my alarm! ADT are requesting call out and technical charges to fix their problem and installation that never worked since they put it in last week Thursday! ADT have put my family and property at risk. Called again yesterday and this morning and still waiiting! ADT please cancel my services - come fetch your radio, I am going somewhere else! This is shicking service for a new customer who has paid you and been with you for 10 days! Shocking service! No call back, no service nothing! Still waiting for you manager to call me! Cancel Cancel Cancel please and give my money back! I cannot wait any longer for you!
