MTN doesn't understand the concept of an IPad not receiving an OTP!

<p>We recieve the usual email from MTN monthly where it says that we need to have the OTP sent to our number with MTN in order to recieve our invoice.</p> <p>however the only number we have with MTN is in an IPad which cannot recieve any smses </p> <p> </p> <p>Therefore i sent an email explaining the situation and asking for an alternative to which the consultant rep**** explaining the normal way of doing it , AFTER I told her that the Ipad cannot recieve smses</p> <p> </p> <p>surely there is another way of recieving the OTP so that we can recieve our invoices </p> <p> </p> <p> </p>
