remove the block on y account for online ordering

Hi Vodacom, I have a problem with my account such that i cannot do online orders due to some block on my account and all I get is " go to your nearest Vodastore" i have done it and all 3 that i have been do not have the devises that i need and they all said they wont have them for quiet some time. Is there a way a block on my profile can be remove for ease of ordering please, that is my profile that i pay for and surely this means am missing on deals coz of an system error? that no one cannot fix?
