Unwanted contact & unprofessional staff

Not sure where this company got my details from as I did not contact them. I was cold-called and offered a cellular contract. At first I showed interest, listened to the sales pitch and asked them to call me later in the day. After reading all the comments about them here on Hello Peter I decided it was not worth it. When the consultant called me back I said I was not interested. Within the next 2 hours I received 7 calls from different Blue Label consultants offering me a contract! One of the consultants even put the phone down in my ear when I asked her to ensure they take my name off their contact list.
