Has anyone else received a call from someone claiming to handle AT&T renewals or "QOS renewal"? We initially assumed the caller was our new account executive because we had recently lost our longtime representative. However, they could not provide basic details such as our complete account number or the email address associated with the account. After we pressed them, they admitted they were not directly employed by AT&T and claimed to work for an "AT&T contractor" called Link Bridge Networks. They provided an address using the domain fiber-retention.com and asked us to sign a Letter of Authorization. Has anyone verified whether this is an actual AT&T contractor? I'm concerned the authorization would allow them to take over or resell our existing services under a different arrangement.

Our company keeps a list of the representatives assigned to each service, including their verified names and addresses. If someone calls unexpectedly, we ask for those details and independently confirm them before discussing the account. If they cannot clearly explain their relationship with AT&T, we end the call and report the solicitation.
This is very likely a reseller or broker. They may be a legitimate third party, but that does not mean you should sign anything. I only handle renewals through a representative whose identity and contact details I can verify directly with AT&T.
I’ve had supposed AT&T contractors repeatedly call from different numbers about renewals. The safest approach is to let unknown numbers go to voicemail and have staff forward anything that sounds like an account change to a known representative. Legitimate or not, these callers often use aggressive sales tactics.
A Letter of Authorization can give a company permission to manage or transfer your account. Some resellers use these calls to move customers onto their own contracts while continuing to provide essentially the same service, so I would not sign it without confirming everything through your normal AT&T channel.

I had a similar caller claim to work with AT&T, then pivot into saying AT&T might not be a good fit and trying to sell another carrier. Our actual account representative was able to verify the account information, but the call still felt misleading.
