WRONG charge by "Giffgaff.co.uk online store"

[#1]

£15 was taken from my bank account by "giffgaff.co.uk online store" this month.

It is very strange. I checked my bank statement yesterday. There are extra £15 was took by "giffgaff.co.uk" for no reason. I have used the £10 goodybag for four months; I topped up every month by my debit card, when the goodybay is expired. The goodybag money is usually took by the "giffgaff.com online store" .  But this month two amounts of money have been taken by giffgaff.com (£10 goodybag) and giffgaff.co.uk (£15).

I need to find out the reason. If it is wrong charge, I want my money back.

you need to contact an agent and ask them whats gone on.

if they are no help, your bank might be able to help you do a chargeback on the funds. you would have to ask them.

but get in contact with the agents first.

Have a look under My giffgaff's transaction history page. In the event of an error, you will need to contact an agent using the link under My giffgaff.

Sounds like a job for an agent but it does seem odd.
