Default Consistent retrieval of same messages

Friends, I am having QMobile Noir A2(Pakistan Company) smartphone. The problem I always face is that I receive same messages for about 10 to 15 times a day. This further results in the delay of the latest messages. I tried changing my SIM card in other phone, it works perfectly fine. I even tried to go with factory reset but still..... No cure!
Please help!!!
