EA account data can't be downloaded, for more than a week.

EA account data can't be downloaded, and it has been maintained in the "preparing data" stage for more than a week. It can't be downloaded or even canceled.I have asked the customer service team three times, but the customer service team did not answer the question and only asked me to request through self-service operation. I have already requested and got stuck in that interface. My mobile phone and computer are completely clean, and it is not a problem with my network. How can I solve it?
