<human>: For months I've been getting these calls on my cellphone from people (probably collectors) asking if they could speak with some lady that I don't know. Even if it's not the girl, it's still the same last name every time. No matter how many times I tell them that she or he doesn't own this phone number anymore, they say that they'll "update the information" but they all still keep calling back every other week.

I don't want to offend anyone, but I've noticed that every time it's someone with an Indian accent. There seems to be several different numbers calling but sometimes it's a number that has called before. To be honest though, I don't know whether it *is* the same people calling or if it's from different companies or something. The fact that every time without fail it's someone with that accent, it just adds to my confusion about what's going on. Regardless,  I'm losing my patience and lately it's been hard to keep my cool whenever they call.

So I registered my cellphone number at a website called "donotcall.gov" since my friend recommended it. I'm not completely sure what it does exactly, but he said that the callers could get fined for calling that number while it's registered on that list. However today I got yet another call from a person with an Indian accent, asking for this lady like always. I did my best to calmly tell him that she doesn't own the phone number anymore, and that he could get fined since I registered on the donotcall.gov site. He said something I didn't hear and hung up. 

However to me it feels like these calls won't stop even if I am registered on that site. I'm unemployed and have been waiting for a call from the job I applied to, so that and the depression I've been having lately adds to my frustration when I find out it's the collectors again.

Condense the text into a few key points
<bot>: What's the best way to stop these annoying calls from the collectors? Do I have to get a new number or is there a simpler way to do it that doesn't require a number change?
