I had this issue with Amex onetime. Apparently their reasoning was that since I did not sign for the purchase (under X Dollars) a diffent dispute process needs to be handled and can only be done over the phone.

The CRAs use their electronic system, called e-Oscar, to forward to furnishers a copy of your dispute, and to receive their results of their investigation, in well over 90% of disputes.  The only manual involvement is the clerical entry of the dispute for forwarding to the furnisher, and the review of their response.

In the event they see need for additional manual review, it can involve more time.

However, they are required, under FCRA 611, to conclude their reinvestigation within (normally) 30 days of receipt of your dispute, so they cannot use that as basis for extending the time for conclusion of your dispute.  They must conclude their reinvestigation within 30 days, and send your Notice of Results of Reinvestigation within 5 days thereafter.
