Why would I have a £100 refund from HM courts?

As The title suggests really. Have discovered that HMCOURTS-SVS.GOV deposited £100 in to my account yesterday!
I paid a speeding fine for exh about 4 months ago which was £100but that was from a different account. Anyone heard of this before?

Haven’t got summons yet but everyone in this thread has said they did. However I’ve recently moved house, don’t know if this might cause a delay. I’ll let you know if I receive one.
