No Value Added Service

I have been trying to activate INSTANT TOP UP, on my line now for 3 days without success, this is the Instant Top Up which is Billed to my account each month, the error message when trying to use the service is THIS ACCOUNT IS NOT PROVISIONED FOR INSTANT TOP UP, Please contact customer Service to activate. To take note, i am not trying to activate Vodacom Express recharge with a voucher, i am trying to access the INSTANT TOP UP SERVICE, where it is billed to my account each month, Well for 3 days now the agents have been batteling to get it activated with no success, on the system it shows the value added service is activated but when i try use the service, it gives a error message that my account is not PROVISIONED FOR THE SERVICE, agents have tried refressing my sim card, de activating and activating my services, with no luck, switching my phone off and back on, does not work, i cant even transfer DATA to my wife's phone, error messages all the way, agents have advised that the sim card might not have been properly activated, each one has a different view of what the problem might be, i am so dissapointed in everything, i asked if i can migrate to a better package that does not just include Data, i'm advised its NOT ALLOWED ? WHY ? ? At the end of the day i will be paying for what i have and use ?? Why cant customers be satisfied and have the opportunity to have what we want ? We are paying for it at the end of the day ? This value added Service INSTANT TOP UP , obviously gets debited from my monthly bill, why cant i be Provisioned for it and be allowed to use it ? The other thing i noticed was that suddenly all notification sms's and communications from Vodacom comes through on my other Vodacom Pre Paid Number ? No one has any clue why this is happening, numbers linked or what the problem might be, Seriously please can someone look into this whole issue and resolve this properly so that i can at least enjoy my Services from Vodacom again ? Please, anyone assist me in this matter to resolve.
