Fake callback requests from the site, has anyone experienced this?

Question

Electronic commerce

Good afternoon.
In recent days, fake callback requests began to come regularly from one of the sites (online store) (they called the specified numbers, people did not order a call). Requests arrive at about the same time, letters arrive between one and 1.5 hours, all containing a number in the codes 495/499 and male names. Phones are sometimes repeated. Spam content requests do not contain.
Has anyone experienced something similar? Maybe someone understands the meaning of such fake requests. Phones seem to be normal, without "paid" codes. The intrigues of competitors?
Addition: requests were sent from different ip from the Russian Federation.

Answer 1

Block by IP. I don’t think that there will be many specialists who will change IP
