Rediculous data usage

[Chrisc]

Having changed my tariff to the 2gb data tariff 3 weeks ago I’ve had nothing but issues and poor customer service with empty promises.
Prior to the Chang over my monthly average of usage was 600gb only. On the new 2gb allowance the data lasted two weeks. I added another fb bolt on and that lasted 3days. Another 500mb got me to today.
How on earth can this be correct ?
Same phone with no setting change and no change whatsoever in usage behaviour. Fobbed off at Customer Service. They had no answer. Finally they agreed to revert to old tariff. That was promised to take effect 3 days ago. Guess what ? Nothing happened. 10 years with O2 and disgusted.

@Chrisc  Have you downloaded any new apps recently, or do you have Facebook running in the background? You'll have to speak to customer service again regarding going back to your old data plan. We are all customers here, and cannot help regarding account issues.

No new apps not sure about FB but if it is, it was before too !
When you say running in the background should I sign out every time I leave it ?

@Chrisc  Facebook is a huge data hog, so the answer to your question is a definite yes. You should also turn off your mobile data in settings if you're not in need of it, and use WiFi whenever you can.

Thanks I’ll do that.
Just don’t understand how my data usage has gone from 600mb month to over 3GB since I changed tariff?
Seem nuts or a con ?

@Chrisc  I agree it does sound a little strange, as your habits haven't changed, but as said, speak to customer service again, or possibly call into an O2 store if you have one nearby, and hopefully someone can help you resolve this. If you do figure out what the problem is, please come back and let us know. Best of luck.

Have you looked on your phone to see what is using your data?
