MTN failing to activate new contract for 10 days....

I purchased an mtn sim card online at the beginning of the month, which was delivered a week a later. And have called mtn to activate the simcard they are unable to activate it they are saying it has RICA problems but when I ask if they will charge me end of the month for the simcard that is not working they are saying yes 80% of the amount i would have paid if the simcard had started working beginning of the month. They don't even give a reference number when you call their callcentre.Yet in the meantime they don't want me to cancel the contract with them and they also can't activate the sim. mtn is terrible...Let's just stick other networks no matter how good their deals sound no...
