Bad Service and Treatment is not the same from people who's on contract and month to month

My Router becomes damage and called vodacom and the person who was assisting me told that because im on month to month in order for vodacom to assist me quicker i must start the new contract for 24 month and I refuse and i ask her that why they don't treat us the same because on a month to month im paying more than a person who's on contract then she told me that in a business point of view the first prority is someone who's on contract i hate Vodacom and im going to cancel my contract with them.
