Incorrect Route Loaded on weekly Card

On Monday afternoon I bought a weekly bus ticket to travel from Delft to Tygervalley. The agent in belville where I bought the ticket made a mistake and loaded Nyanga to Tygervalley. I only realized this when I was boarding a bus the next morning, the driver advised me that the route on the card is incorrect and I was unable to board the bus. I went back to the agent who sold me the ticket and he gave a terrible attitude and blatantly told me he is not going to help me, he was extremely rude. I called Golden Arrow and I was transferred to Micheal Stevens who did not give me a second to explain my situation and basically told me to go back to the agent that sold me the wrong ticket. This after I have told Mr Stevens that the agent is rude and is refusing to help me or honor his mistake. I am now stuck with a weekly ticket that is useless and Golden Arrow has taken my money and are refusing to change my route. I am extremely inconvenienced because I have to pay Golden Arrow extra money while they are seating with my weekly ticket money. I am extremely annoyed by this company and I know if I go back to that agent in bellvile he is not going to help me as he had previously told me so.
