The cheapest option would be to order a new, longer, length of cable, plus two terminal kits, one male, one female. It's about half an hour or so's work to strip both connectors, cut off and discard the existing terminals at the vehicle end and cable and crimp up a new length of cable with new terminals plus a new male connector.
Just costed this up, and the parts needed are:
Female terminal set (vehicle end), for 6mm² cable:
Female connector terminal set - evChargeking €20.62 plus tax and shipping
3m of 6mm² cable:
Charging cable - Single Phase - 32A - evChargeking €24.79 plus tax and shipping
Male 32A connector with 16mm backend:
Male Type 2 connector - evChargeking €73.55 plus tax and shipping.
Might be worth asking them if they can supply just the male connector terminals, as that might be cheaper.
All that's needed then is some patience and a proper crimping tool to assemble things. I'd do it for you, but it's a bit far from here to where you are. Worth asking Erwin Raets at EV Charge king if he will take your old cable back and use the parts to make up a new one, perhaps.
