Funds not Refunded on Online Order (Poor Customer Service)

I cancelled an online order in April. Till today I have not been refunded. I have called multiple times regarding a follow up of the refund (***). The call agents keep telling me that my refund will be processed in the next 3-5 days. 3 months later, my refund still has not been processed. The service I have been getting is appalling and having to call only to be told the same excuse over and over again is frustrating. I am tired of chasing up with the Game online order department. If I do not receive my refunds in the next week as promised, this matter will be taken to social media.
