I have a Storm 9530 and out of the blue the phone dial pad stopped working.  When I select the dial pad from the phone homescreen, the numbers are there but do not respond when I push one.  Another quark, when I access voicemail, the number pad is different.  It has an asterik, the numeral 5 and the numeral 1 and a 0.   I cannot delete any messages and now my mailbox is full.  I have been to the Verizon store where I purchases my phone twice and am on my third phone.  Anyone have a similar issue and know the fix?
