I bought a top up for € 15 at a super market, but the code isn't working. I went back there, but they don't speak any English, and they said that they cant do anything.
When I try to top up with the code I get both this messages:
"The secret number you entered is invalid"
"The voucher code is not valid please repeat the entry"
The first one I get when I use speed dial, and the second one I get when I use either the website or mobile app.
Can someone help me?
