Failure to perform a SIM swap

It has been a month now going back and forth every day to the Telkom Mobile store at Mall of the North to have my SIM swap done. Unfortunately even today the service provider still says they are unable to perform that due to a system error. <br> <br> I am on the Internet 5 promo with 10GB of data every month for R199 and i had to buy a data from the very expensive Vodacom ISP to cover for my data needs for the month. this is the second time in the duration of my contract i have had this issue and the the last time the made me pay for the services with even me using them. <br> <br> This is just driving me crazy<br>
