Bad service

I have an access facility with capitec which the insurance has been paying for the past 24months since i am retrenchment, as per the contract they only pay for 24months en decided to call them to get the settlement amount for the remaining balancet off. My problem with capitec is that they I'm struggling to get to close the account and it is now accumulating internet of which i wont pay because i have been calling to request for an account closure and they are sending me from pillar to post. I am not happy with their service at all
