Cancellation Trauma

I'm so frustrated with your customer service. I want to cancel my month to month router contract due to financial challenges. Firstly I was advised by your cancellation department that they would only cancel once the router has been returned to the branch and given the RMS number and signed the cancellation forms. On Thursday 28 March I went to your Store at President Square Krugersdorp, and they assisted me with the cancellation forms and advised that I mail the document to the cancellation department. Today 03 April after getting through the 5th Department to cancel now I'm being told to go back to the branch and the Agent who assisted me must cancel the contract I explained to the Agent that I can only go to the Branch on a weekend as I work from 8 to 5 and she said they don't work on weekend and I should make a plan to leave work early. And making a plan its not possible as we came back from the holidays, right now i regret taking a contract with your company, had i know that it will be a mission to cancel with you I wouldn't have bothered myself.
