Unable to deactivate sms roaming

<p>Returned from overseas 30 hours ago. Immediately sent deactivation sms to the 31050 number and still can't make or receive local calls. Spent more than 40min to get through to a 'consultant' on the help line who 'escalated' the query and still not able to make any calls. Apart from the non-solving of the problem the customer service was unsatisfactory - it;s not acceptable to wait >15min for a call centre call to be answered</p> <p> </p>
