ANOTHER ENRAGED VODACOM CUSTOMER

In September 2017 my contract expired with Vodacom. I called them to cancel this contract because it was too expensive, instead I was offered a downgrade option at a discounted price of R110 worth airtime this without a handset, in order to retain me as a customer. However after upteen calls the past six months because Iam not satisfied with this option & another call on 12/02/2018 insisting that I want to cancel this contract in favour of a more comprehensive option, I was told it would cost me 18 months worth of penalty fee. None of the original or previous consultants ever mentioned a penalty fee for cancelling- only now that I insist I do not want this mickymouse option do I get told it will cost 18month of penalty fee. They are not providing me with an adequate service. I was prepared to enter into a more suitable contract in order to obtain a more comprehensive service which would suit my needs & this is the inadequate, inefficient service that Vodacom offers...NB! the most expensive service provider of this nature. What penalty am I being charged for? Iam not paying-off a handset!!! What must one do to get GOOD SERVICE??? Perhaps the next step is CONSUMER COUNCIL & OMBUDS, I know Iam not the only customer with this type of complaint. WHAT NOW???
