Traction battery failures in EVs are thankfully rare, but understandably they are expensive and time-consuming to replace should the worst happen. It is disappointing that it has taken such a long time for the issue to be diagnosed and we would have hoped that you would have been supplied with a courtesy car in the first instance, but would caveat this with diagnosing a failed traction battery would require a specialist technician - and that a new traction battery could cost £10,000 or more. Add in the significant labour of replacing it, which could take two days or more, and having all this work completed at a relatively modest cost to you is not the worst possible outcome.

If you are unhappy with the service you have received you can make a written complaint to the dealer principal and if necessary you could escalate this to UK HQ of the manufacturer or to a trade body if the dealer is a member.
