What should I do with an unwanted (no longer needed) full (100% unused) available PayPal Credit ?

[LordBucketHead]

A bad experience with a unreliable & untrustworthy trader ended with a full refund to my PayPal Credit.

I'd specifically opened the PayPal Credit for the purpose of this purchase and no longer need it.

What steps if any should I take now ? Will I incur PayPal charges if I do nothing ?

Thanks for reading.
