Mtn
What did they mean by access for life

I registered my mtn sim card access for life, i left the country and return only to be told my number has been recycled. I registered my email address and my cell phone number is linked to my bank account and other relevant contacts which I had synchronised to their server which I remember I was charged for it. Its better they tell us we dont give access for sim cards, the most terrible aspect is their call centre agents "some" lack manners others are the worst part of life
