Delivery of LTE modem already 1.5 months late

I responded to an internet advert for a 24 month LTE contract. I had to apply about 7 times before I was called to do credit checks, confirm bank details and provide other information. After a long time on the phone, the Telkom person confirmed that all is in order and my LTE modem would be delivered within a couple of days. I received an email confirmation of my successful application on 25 February 2016. It is now 1.5 months later. All my efforts with Telkom staff over the phone have not solved the problem. I went to Telkom Menlyn. The staff were unfriendly and said they could not help me. I am very disappointed with Telkom.
