I mean why do I need to pay for the ring back tone that another person listens to? Giving money to celebs to buy range rover and G-wagon, and come on social media to insult you. Worse is that they come up with all manner of subscriptions like to get accounting, medical, engineering tips, text bla bla bla to 123; politics is a dirty game, to know how dirty your LGA politics is, text LGAPOL to 123. Wetin!!! When they find out your are not falling for their tricks, they go behind your back to activate it for you. Then when you call them to deactivate these services they lie to you that its been deactivated whereas they did not.

Well, everyday for the thief, today is for the house owner. To deactivate all these useless ring back tones simply dial *123*5*1# and reply with the number "2" then enter the serial number corresponding to your active subscription and enter the number "1". Shikina!!!
Repeat the steps for multiple subscriptions. The economy is not smiling at all, so no room for unhealthy deductions.
