Dispute re eBay fees

[marcarlin-0]

Good morning,
Can I please have response to my complaint?
You were supposed to have responded within 72hrs and have not done so which is unacceptable.
My bank account has been debited to the tune of £5.92 after selling one item, when it should have been £1 which I signed up for under the Sell for pound promotion.
I look forward to your response and comment

If this was the Hornby coaches, it was a multiple listing,

£1 offer is only for single item listings, so you pay full 10%, all explained in T&C's.
