SMS from 122 keeps taking out my extras credit every 5-60 mins without my knowloge

I've recently signed up to optus prepaid on Friday by bring my existing number to Optus Prepaid.

I've keep getting text message From Optus saying "An SMS you tried to send or receive has failed as you are out of credit for that message type. Recharge Now to allow future SMS message to be sent or received".  Every 5-10-30-60 mins which really drives me crazy. When I logged into my account on the Desktop Verison there a lot of SMS sent to 122 which I don't even touch this number in the past however.

Optus Rep: Turned Off premium Service for Now

Even the premium Service turn off I still keep geting sms out of credit message.

I was reading in Whirlpool that 122 is Optus Marketing Number.

I've fixed my phone had to a factory reset. I check my usage it's seems all good now.

It's might be app that had a Virus that could cause the problem.
