Just to clarify, you are tethering your data on your phone or are you reverse tethering your PC internet access?
When you contacted your carrier/network, did they confirmed that you've used that amount of data? if you did, perhaps there were other programs running in your computer that uploaded, downloaded, etc or even watching movies or videos.
ermm my phone data got quaota around 3GB and i only use around 100~300MB for online game purpose on my pc if i use for 42GB it should block by now...the "tethering and portable hotspot" still show usage 42GB.
when i sms check balance i still got 800MB left before it finish up...ahh i dont really care as long this doesn't effect my data usage and phone its ok but still...got confuse how much i already use so i need manual check on my carrier using sms every time.
