I want to receive all the messages

I want to receive all the messages Yesterday i called MTN having a query about messages from any money market like Absa Bank cash send and standard bank, I don't receive those messages on my phone but I receive other SMSs, the consultant say I must restart the phone, today I called and the consultant called Lwandile Lushaba said she can't help me. I think they know about this why they can't help me My No. ***
