Disgusting Service

We have signed a 12 month contract for fiber in the interim we have been given a LTE router which was cancelled by vodacom which we are not aware of. We have spoken to a number of people in the call centre but no one knew what was happening. Now I get transferred from a team leader to a sales department that is.now closed. I have been on the phone with vodacom for 2 days trying to connect to a service that was cancelled. I would like to cancel my service with immediate effect!! I could not get a reference number because vodacom system will log a technical call for the line.
