bad service

Good day I would like to complain about the service received from hot spotter consultant, when I accepted the contract I did mention that my debit order date should be the 27th and she noted that it will be updated on their system .When I received the email deduction date it says the 25th I called them immediately and I was advised that hot spotter is the 3rd party I should call mtn to rectify it , when I requested for the contract to be cancelled I was advised that I will receive an email or sms to confirm the cancellation .And please I am no longer interested I want out.
