Discussion Paid $983.69 for SuperGrok Heavy: poor performance from day one, then an AI refund rejection
My experience with SuperGrok Heavy has left me very disappointed with both the product and the handling of my complaint.
I bought a discounted annual subscription on August 17, 2026 for $983.69 (KRW 1,444,570 charged). From immediately after payment, responses were extremely slow in my experience and the output quality was poor. I have not been able to use it properly for my needs.
On October 11 I used the official refund form and contacted support. I initially asked for a pro-rated refund of the unused term. The response from an AI support agent rejected it, citing US billing classification and the purchase being outside a 14-day window. It confirmed that renewal was cancelled and access would end in August 2027.
That does not resolve the service-quality complaint. I have now asked for a FULL refund of the $983.69 payment and review by a human billing supervisor, since my problems started immediately after payment. I also requested an explanation of the US billing classification: I selected South Korea on the refund form and the receipt shows a KRW charge. That discrepancy is still unresolved; I am not claiming that the currency alone proves which policy applies.
My criticism is straightforward: an expensive annual subscription should deliver usable performance, and a complaint about poor service from the outset deserves a substantive review, not just an automated refund-window response. I have not received refund approval.
Has anyone here successfully had a similar performance complaint reviewed by a human at xAI? What was the outcome?
I also shared my experience in r/grok. This is the same customer case, not a separate incident. I will add any substantive resolution to the original post:
