Rewards Co review: Cell phone contract

This company keeps calling and insists on upgrading or migrating my contract. I don't know who they are and how they got my contacts.. But they a deceptive and scam company.. This woman insists that paying r400 a month is cheaper then r200 a month.. I person my the name of charmaine called the last time and my 4yr old answered and she was trying to sell him a contract.. This company should be closed down. How does a company list this exist..

Certainly nothing ethical about this company..
