blackberry bis

Hi,from last week Thursday morning,i was unable to connect to my BIS subsciption via the USSD code,it was deducting my prepaid account and then the airtime was put back onto my account again,i phone the call centr to find out why it happened and i was told that they were experiencing problems from their technicial department and that they were working on the problem,they even gave me a case number:REF ***2 and was told that the issue will be resolved in 72 hours,i phoned them again yesterday to follow up on the issue and was told again that the technicial department was still working on the problem,remember i was told that the issue would've been resolved in 72 hours after call was logged,again this morning and just now i phoned again and was told the same thing that the technical department is still working on the issue,my problem with this issue is that they didn't tell me what the technical issues were with there system and why the blackberry BIS system was offline,out of good gestures ain't they supposed to send messages advising us as the customer on the progress of the problem and how far their technicial department are with the problem.
