Question about Vodafone Contract (and how to check how many texts and minutes

i've used)? Okay, so i got a Vodafone Contract (UK) On friday, and yes, i have used ALOT of texts and i know i've used like 10 minutes and thats it, i've called 191 and they send me a text message but it just says:
Balance-Enq:24/10/10*
Last Call:(none)*Amt-Unbilled: £0.00
*Minutes-Used:0.00
*SMS-Sent:0
*MMS-Sent:0-Used:0.0MB
Like/ what the heck? I know i've used more Minutes and sent more texts, any other way i can check it :S
&i've deleted some texts i've sent/recieved
