Misrepresentation just to make a sale

I took an LTE contract in January and i was told by the Consultant that i should pay R800 as a refundable deposit after 3 Months but now they are saying i can only get the deposit after 24 Months???I am so angry because what will be R800 after 24 Months plus that incorrect advice, misrepresentation and non disclosure on their part otherwise I wouldn’t have taken the contract if i knew that the deposit was going to be paid after 24 Months. I am soo not happy about this. That purely lack of honesty and integrity, revolting!!!??
