Our FR10 main package is complete, with its fitted adapter checked. The extra adapter in the promised spare kit is absent. Twenty days of next shipment replies, no parcel reference. I want the seller to answer that additional item without reopening the main delivery discussion.
Ask whether the exact spare adapter is physically available, then ask for a separate supply proposal. Next shipment is rather convenient when nobody has to say what goes in it.
Get that shortage acknowledged on the order balance. Then compare a real manufacturing offer with a defined credit and the cost of an identified replacement, not another promise in the main delivery thread.
Balance corrected. Seller offers credit or manufacture without a firm availability date. Maintenance is pricing the complete approved spare assembly before we choose.
