MTN is in trouble for those who are still njoying the 33,000 tweak continue,

For those who are eligible before it is 30 and otherwise 50
Steps:
1. Dail *142#
2. You would see a prompt with make mtn to mtn free calls for 50
3. Reply with 1
4. You might get an error message like "Transaction failed, please try again"
5. You would get  a confirmation message 4rm MTN instantly
