I am getting sick of this, please offer me a solution

for the past 2-3 months I get called by this number 0366106035 every fucking day, somedays even 2 3 times , but today the idiots have gone too far with this .. they called me atleast 5 times,

I tried to speak with them ... but I don`t understand shit of what they are talking(kind of indian accent) , they are saying hello hello , and when I ask them what do they want , wait for 4-5 seconds and just close.

I have tried to talk them nicely and say to stop calling me .. they just hang up , I have told them to fuck themselevs same thing. I start to think they are retarted.

Can you offer a solution for this shit so they can not call me again, I have this number for over 6 years now, and I really don`t want to give up on the number.

Send a hitman, worked for me

Call your mobile service provider and block that number...simple as that

If its a droid, I think you can get an app that blocks numbers from calling or txtn you, not sure how well it works though,
in theory, the number has to still make it to your cell before the app can see it to block it.
