Telkonfusion - False advertising

Took out a new contract with Telkom and: 1) Have been invoiced for a full month's service, when I enquired and was told that it would be pro-rata for the month. (3 days, and have been invoiced for full month) 2) Was told that they would contact me to pick up my Mi-Fi Router (part of the deal) and its been nearly three weeks and still waiting. 3) My contract includes 3x10Gb (besides my 1Gb (free me) and 2Gb fro whatsapp, I do not have the 3x10Gb loaded on my profile, and have been invoiced for going over my monthly internet bundle. How can for somethings the pro-rata work and for others not?? 4) Impossible to get through on the phone, use their online chat and get told to speak to another department. I should have learnt from previous experience, but was hoping that these issues would not happen!
