Duplicate debit transaction for a single top up

[Angus1]

I did a top up of £10 at early August and last week saw 2 debit transactions on my debit card statement having the same reference, how can I tell O2 to check? Any email address or portal for that?

Thanks.

Hi @Angus1 - you'll have to call one of the numbers in here and talk to O2 directly: Guide: Coronavirus Community Help and Support 

Calling around 08:15 UK time seems to get the best and quickest answers.

Good luck.
