I topped up my plan today by 15 euro, then tried to top up by 15 again to give myself credit for an add-on (why can't you just directly buy add-ons??)
The second top up just went straight into reactivating my plan 20 minutes after I topped it up, so 3 have practically stolen 15 euro from me. Is there any way to get it back for get the credit I payed for??
