CREDIT LIMIT from NOWHERE. blocked line

<p>I have had multiple contracts with vodacom for 11 years and have never had issues with credit limits set to my accounts. suddenly yesterday i get a message stating that my credit limit bar has been activated. when i call the call center, everyone has a different story. I CANNOT MAKE CALLS OR ANYTHING and this is absolute BS!! i did not set a credit limit, have not done anything different with vodacom to have to deal with this sorry state of affairs. i need this sorted. i need someone to tell me what is going on and lift this credit limit story on m y account. i cannot fulfill my job role, cannot call in an emergency!!! i havenever missed payments via debit order with vodacom for 11 years and then suddenly without warning i cannot use services i pay for!!! sort it out or switch away from your hopeless new 3D system</p>
