Sometimes, the header looks irrelevant to the company registration name.
However, most companies submit Sender-IDs which are relevant to their brand names (which are different from the registered name). In these cases, you can drop an email with supporting documents to the operator’s support email ID mentioned in the portal.
In case you still don’t hear from the operator, you can forward that email to your Kaleyra Account manager and we will do our best to get this expedited for you.
