MTN cancels Data sharing without informing customers !!!!!!

MTN took it upon themselves to cancel data sharing without notifying their contract holders verbally or in writing. I have been a loyal MTN user for years. This is against the National Credit Act. This is SNEAKY !!!!! Please reinstate data sharing or allow contract holders an opt out of contact choice to go to another service provider who will better suite their needs. What kind of service is this? You cant change a customers contract conditions until the contract has come to an end. This is disgusting !!!!
