soli, bai - bai

i got so frustrated with all these nonsense phone calls. From the 1st day i installed my phone, there are more than 10 calls trying to sell something. Even my mobile phone gets that too and worst thing i have to pay when i pick up the call. So i decided not to pick up any calls either from my house phone or my mobile unless it is with an indicated phone number from my phone book.
I dont understand how they get the phone number from. Worry that my mom or my brother will call i normally pick up call in the morning where there is possible time that they will call from KL.. and i got so frustrated when i got those nonsense call .. i just SHOUT.. SOLI i dont speak English, BAI-BAI..
