Why must you lie to land a deal

Hi there. My dad has been contacted regarding a contractual agreement with T-Connect on behalf of Telkom. the deal was that he would get a 4MB connection UNCAPPED with no throttling, no shaping, no softcap, no FUP (fair use policy), and he would get a modem and wifi extender and a LIT tv Box. I have now since checked on the customer portal and low and behold, there is a FUP, then I believe this would be breach of contract yes? I would like to have the service cancelled and returned to its normal state as this is not what we signed up for. if this is not resolved, this will be taken to the Obudsman on the grounds of false advertising and misleading information. I ask that you please contact me and advise how to go back to just have the ADSL line with you guys, cancel this ********** contractual agreement which is in breach and make sure that any monies taken is returned please. I look forward to your response URGENTLY.

Regards
