On air false adverti*****t ****ming a pensioner

I was called by a customer rep and they explained the package was only 299 including the dstv explora but then they proceeded to deduct 224 each month,which is false adverti*****t and I called them and ask them to cancel the subscription and she stated she cannot because 7 days have passed already and they cannot ,it is unacceptable and if the listen to the conversation with the person from on air they would hear that they did not explain it is every month they are depting my account i am a pensioner and they must come collect this box and reimburse my money as I made no use of it and they are using dstv name but their service is terrible when it comes to helping you when you have such a problem but very nice when they advertising the product leaving important information out .
