Yes,its a good idea to store the numbers (see my earlier post) as "Do Not Answer" on your phone. Yes, its annoying, but just ignore them and don't answer the call. after a while they will give up. If you answer and tell them to stop calling, they will just keep pestering you. I think they work on commission and quotas even if you don't pick up, and so they try to call as many numbers as possible.

The calls are coming from Wyndham Vaction Resorts, the call me every week.

These people are like stalkers, I have told them repeatedly not to call. I have 2 young babies and I now have to leave my phone ringer on silent to stop the disruption - I am even missing calls now due to this. I am sick of it!! These people should be banned from recalling - it is always the same number. And since I told them where to go, they are calling me 5-10 times a day like they are angry or something. When i answer they do not even speak - they know they are harassing.

Heaps of calls from them no messages - annoying

I too had several missed calls a day from this number
When u try to call back - u cant
When i did answer very noisy background with non english speaking telmarkter

yep definitely Wyndam, they've been calling me 4+ times per day without leaving any message. I have now added them as a contact in my phone called "Don't Answer". I'd love to report them for this harrassment but don't know how, anyone?
