Harassment by debt easy debt solutions

I was contacted today by them, when asking them why they phoned me or in what way did I give permission for them to contact me they replyd that the numbers are obtained from the national data base {itc} and that I should read the fine print on my debt applications, on this I asked her to stop contacting me, then I get 4 calls in 5 min from them by difrant agents, this is harassment and if I only knew where to report this place I would do so in a heartbeat, reading the rest of the reviews on here these peaple need to be taught a lesson, this is not right what they are doing and should not be allowed to continue
