Cheated/Bad Attitude/False Advertising

After applying for an add-on contract on 31 December 2014, I was sold a faulty device which took Telkom about 7 days for them to activate the line, after which I found out that the device was faulty. I tried to return the device and was told I had exceeded the 7 days return policy. After a long battle with the Manager at Cresta, he accepted to take the device back and I asked for that order to be cancelled and start a new process for a different brand. It took more than 6 weeks to get a replacement order, and all the time getting bad attitude. I have all the emails to this effect. I asked for a Smartplan 50 as per Telkom's brochure, it has 50 minutes and free calls to Telkom mobile numbers. I only found out that it was not so last week after my call was terminated whilst talking to someone on a telkom number, due to insufficient airtime. Upon querying this, I was informed that I am on a Smartsaver 50 and hence, If I want the free calls, I have to fork out R49 extra on my contract monthly. I want to know where in the Telkom brochure does it say there is a smartsaver at an extra charge. I only see 2 options of smartplan 100 and smartplan 50, of which I already have a smartplan 100.
