Can you post a picture of the connector you're querying?
I suspect the answer is going to be that you need to book a non-fault callout for £25. This can be done by following the same routes (phone or waiting here) as if you had a fault - but that the appointment is chargeable rather than FOC.
If you can post up a picture of the connector in question, we can advise further.
