Is the membership import of Keyun superimposed or accumulated?

Accumulated, this is a friend's evaluation of customers like a cloud: it's really a garbage customer like a cloud. We don't know how many pits there are until we use them. I upgraded the system, and the member SMS I bought in the last system disappeared directly. I called customer service, and people said, we can't handle this problem. If the SMS has been used, we can't refund it. 10 thousand conditional text messages, there are more than 6 thousand left, so it's gone? Who is the boss looking for me this afternoon? This kind of after-sales garbage has no bottom line, which is really a bold sentence. If you can't return it, you can't return it. It's over. Please buy carefully! The machines in this company are really not good, the after-sales service is very difficult, the employees leave their jobs quickly and no one can be found.

I hope it helps you.
