I added on a website an external lib that called via inclusion of script, ie a js that made the communication with the services that this company offered. After this inclusion they would add the information on the page.
So far so good, but now we terminate the contract and I removed the inclusion of this external js of them, but I do not know how it is still loaded on the site is like a cache but it does not make sense being that I removed the inclusion of this script, they would know why and how to solve it?
