Here, it is the customer's choice, whether they want to take them to the Comcast office, have them picked up by a Comcast tech., or have Comcast send a parcel box/label for the customer to send them back; I wouldn't use the latter, indeed due to no receipt for the cable boxes and/or modems.
The first two choices are equally fine, as they would give the customer a receipt in either case.
