The Worst Service Provider Who Changes The Contact Benefits in the Middle of the Contract

My husband resigned a contract with them in Nov last year where he could share his data with me. Today the dara sharing was cancelled. When he called to enquire he was told that you can only share your data with a contract number and not prepaid!!! Are you guys even right in your head MTN???? Why would a person need to share data with a contract number!!!!! When we ask the agent how could they do that when we signed a contract she couldn't answer!!! We will definitely be porting our number after being with them for years!!!!!
