ADT obviously has too many clients

ADT obviously has FAR too many clients to want to keep the clients they have. exactly a week ago, i filled in a form as i am moving house. i stated on my form that i would want adt at my new premises and that i would like someone to contact me. up till now, no one has bothered. so i assume i should go for EC Security as they seem to be VERY keen for the business. Sad seeing as though i have been a loyal ADT client for almost 10 years
