Poor Customer service Vodacom

I took a contract phone at gateway Vodacom shop sometime in 2020. I had a horrible experience with them which led me into canceling my contract before it finishes. I went to Gateway vodacom shop to pay for my cancelation.. And they charged me more than I was supposed to pay they told me they can't give me a refund because the money Is already banked I went on Facebook complained about their poor service they promised to give me a refund only for their rude agressive agent to give me a call telling me vodacom is not owing me any money I regret associating my self with such a company... I wouldn't even be putting any rating..
