They do not take NO for an answer. I partially signed up to look at their website and now they won't leave me alone. They 2 -3 calls a day. They continue to call all hours of the day and night even though I have asked 20 times plus to be taken of their call list. I just got a call then 11.58pm. Who calls at that time of night. They never call with the same number. I have blocked them many times. The numbers when you return the calls always are always an invalid number. What company changes the number every time they call? What company doesn't have a call centre answering missed calls or enquiries. They try to convince me to complete the sign up even when I tell them I'm not interested. They keep trying to engage you in conversation and they get annoyed when you tell them you ARE NOT INTERESTED. I have to hang up on them and they keep calling back:-(
