Taobao has no SMS notification. Why is the return unsuccessful?

I have bought things from Taobao for n times, and the number of returns has exceeded 10. I haven't heard of refund and Taobao texting.

Generally, after the refund is successful, Taobao will send an email to tell you that if you bind the email, the refund is successful.

Because you usually swipe your bank card when you buy things, if this is the case, the bank may send you a text message telling you that there is a refund. It depends on the situation of your bank. Some banks will, and some won't.

But even so, it usually takes three working days. It seems that the refund didn't arrive immediately.
