Telkom breaks consumer protection act

So telkom was advertising a package deal for a fibre uncapped 10mbps line with a lot of add tons like month free, line free and a smart tv box. The sale rep said as we are existing clients the deal is for only 650. So we signed up for that deal. They came installed and refused to give us the deal as they claimed it has expired(this was on 22) but on the pamphlets it says ends 31(end of month)

This is wrong and against the consumer protection act!!!!!!!!!!!!!! Telkom now refuses to help me and said they would call me back the next day and have not done so for 4days now
