Discovery my anger !!!

Please help regarding Discovery. I don't even know which branch of Discovery this is, but I am getting five phone calls daily from Discovery. Looking for Rebecca Segeso. Every time I ask to be removed from the system as I am not Rebecca, but this is not being honoured. Have you gone crazy?!?! Leave me alone!!! I am not a client of yours and I dont want to be one. The calls are coming from *** numbers and similar. Remove me immediately from your lists and please dont even contact me to tell me the matter has being resolved. I will know once you stop phoning me.
