Rude sales marketing

Non stop calls from this company is either I answer the call they don't talk or drop the call when I answer. Finally today I found out where is the call from. The no.: *** I have been getting calls form it for quite some time. And I have a question mark that the number they called on is not even mine it was late fathers and is still on his name but surprisingly the consultant asked for me which is rare. I am not even a customer at this company I never bought anything nor order anything before. I have many important calls that I expect not these random calling for sales , worse how rude the consultant was she just marketed and make as if I did order before , and I asked what order?! she said no she is telling, and she continued marketing what they sell and asked me don't I want to order now?!, I said no thank you Dear. She just said "Okay" and drop the call .. That's so confusing because I am not even fami**** with this company as I mentioned above. That was rude and time wasting because I am at work and I don't care if she is doing her job! I prefer you to remove my contact number: *** out of your system thoroughly and I don't need no calls from you in future only I'll make a request, I don't care how but just remove my number! Is unacceptable to just get random calls without even applying for any application that I maybe contacted.
