Order delivery

As a Telkom user I have really been let down this time around. I made an online purchase for the R99 sim card on 3 May 2019 and I have still not received delivery. Whenever I call their service/sales desk I get given different reasons. I received a text on 9 May 2019 with a courier tracking number stating that my order will be delivered within 3-5 working days. I keep calling every second day and every time I get a different response from that the order has not been picked up by the courier company, to apologies and that it has been escalated to management and even told that I will be called back which NEVER had happened. I have ordered online from Telkom in the past and never had to wait this long for delivery. This is really upsetting because I placed this order early in the month and now we are reaching the end of the month and still no delivery.
