Breach of contract

DSTV offered me a pricelock deal and never mentioned that if I was not able to pay for two months they will cancel the contract. Now they have cancelled the contract and expect me to pay 2700 upfront that I clearly do not have hence I was not able to pay for two months. This is very unfair and frankly I think this is done only to us black people because they think we submit to everything including the bad service they render to us.
