Mobile broadband contract

I've signed up for LTE mobile offer online (telephone) on March 24th and agreed to the T&C's.<br> The modem should have been delivered in 5-7 working days from acceptance of offer.<br> The debit order went off on the 28th as agreed, 10 working days past and still no delivery.<br> No reference or correspondence SMS/e-mail form Telkom to even confirm the status of the order.<br> I', still waiting for my tracking number as promised by the call centre on Thursday.<br> Today when I phone I hear that my order is pending?<br> How can a debit order go through but the order is still pending?<br>
