Call back multiple times in 3 min

All i have to say about these guys is that i told their sales person that i wasnt interested in their products a few times and when he didnt take no for an answer i hung up on him and then he proceeded to call me 4 more times back to back and when i asked to talk to his manager he just laughed at me so i hung up for the 4th time and then he called back so i just answered and left the phone on my desk till he decided that i wasnt going to talk to him. all that to say is MR price you just lost a clothing customer as well as a potential subscriber!!
