Trying to complain to Argos but only have transaction id (not order no)

itm2

I am trying to contact Argos regarding a £220 pair of Technics earphones which have become faulty just over a year after I bought them (1 year + 9 days). I am overseas at the moment (for the next week), so telephoning them is not the easiest option.
I have tried using their FB/X/Chat channels, but they are all bots and are requiring me to enter an order number. The only email I have from them (an e-receipt) does not have an order number, only a transaction id - it was reserved online and collected in-store. Does anyone know how I can contact them online in a way which doesn't involve bots?

If you reserved online, do you have an Argos account? I only ever order online and collect from store and I have 45 pages of order history going back to 2016. All have order numbers. If you can find it this way, maybe you can get somewhere with the chats.

Note that as they are over 6 months old the onus is on you to show they were inherently faulty (if you are claimimg under Consumer Rights).

Was there a manufacturers warranty?
