NASHUA CLOSED DOWN, NOT INFORMED, PREMIUMS PAID

Hi i have paid my cell account for january swell as february to nashu mobile, only now to discover that vodacom has taken over my account....and now they want to suspend me for account not paid to them!!! this is crazy, cannot get hold of anyone at nashua, what has happened to their bank account!! I need my premium paid for jan and feb refunded with great urgency! why is none of the numbers we got for nashua working at all, even the emails bounce back! If vodacom took over what about the bank accounts!!! who is checking to see that every single client throughout SA have now paid their installments to Vodacom and no NASHUA!! My number is ***, i paid R813 for jan and R813 for feb????
