Tried to top up my monthly big bundle ,however...

[Zoso]

I was alerted on friday 31st that i needed tp top up £20 by the 4th of april so i didnt lose my roll over minuites data etc .

So i topped up ,bowever instead o2 deducted £10 as a bolt on and is now using the remainding £10 for data etc as the bolt on has ran out apparently .i do not understand what has happened only to say that this is why i normally wait for things to expire as this has been an issue with giff gaff too .You top up before expiry and it seems to think your wanting to purchase something different even tbough they message you to top up ! 

Can anyone help ,im not made of money and i cant afford to do it again ,that would be £40 for this month .is there anytning i can do ? I have only just realised as o2 text telling me i have used £2 of credit for data already : (

Just to say i have had another message from O2 stating i have used all my data from the works bolt on and my next bolt on is available on the 30th april and i will now be charged individually .

I havent changed from my £20 big bundle which i always have so why have o2 changed my montnly bundle ?
