I have a customer in Mexico, which his domain is registered at Telmex company. Until today his hosting as well.
Telmex does not give you the option to change the records by yourself, so I managed to create the necessary A and CNAME records (pointing to Webflow) and asked them to delete the existing A records.
This was 3 days ago and the website is offline and at the managing interface I can still see the old A records.
There are also NS records pointing to their servers. Should I ask them to delete those as well?
Any help would be much appreciated!
