Blocked account for no reason

I am extremely disgusted by the way my query has been handled. My vitality money profile has been blocked, i cannot use my card. I have made 5 phone calls to try to understand why. Every consultant says the account is active and i can use it but i cannot. My last call on 6 May to Ayanda she advised that it is a system error and Larry is working on it and i will receive feedback. I have received nothing and guess what???? My account is still blocked. What is going on? I want any service fees charged this month reversed because my account is not active and is not in arrears but i cannot use it due to no fault of mine. If it cant be resolved immediately i want to close the account
