RUDE CONTACT CENTER AGENTS,UNABLE TO REACH 808 DEPT

I have been trying for over 3 weeks to get hold of the contract department regarding my MTN data contract which I have not been able use. When I try to call from the prepaid sim card it doesn't go through when the agents transfer . I have tried calling from the data contract sim the call still doesn't go through. Your prepaid contact center service agents are very rude they keep giving me the number 081808 even when I tell them am unable to get through to that number all they do is to get rid of the caller , they get irritated and advice they cant assist , no one from them is taking the initiative of assisting further , they are rushing the AHT .I NEED SOME TO CALL ME BACK ASAP , I cant be paying for a s service am not happy with.
