Responses xAI Super Grok 4 - Subscription - 1 Month New/Old Account

The subscription was issued fairly quickly, I used it for 10 days without any problems, but on the 10th day it just disappeared and I was offered to buy it again. The seller looked at it and said he didn ´t know why , but he wasn ´t going to do anything . I spent $10 and used it for 10 days, so think about whether it´s worth buying here.
