Travelstart online Chat are not very helpful and updated

My return flight was cancelled by the airline as I was already on one leg of my flight.According to your online chat agent I'm due a refund as per the fare rules but according to the law if an airline cancel your tickets u are entitled to a full refund.So travelstart could I have my full refund and explain to me why are your chat agents not updated on the refunds law.My refund is also taking a long time to solve i also mentioned that my booking which was done has been cancelled by the bank so I will need alternate refund option.I would love to talk to someone who knows more about the refund process as my ticket was cancelled and I was left stranded by yourll although there were alternative option just to find a way to SA.i have provided a SA telephone number please ask them to forward my number abroad as I'm the one dealing with the complaint.
