Dear Sir/ Madam,

Recently (since last month), on data usage portion, my data running till 9.9GB since I upgraded this IOS 9+ for iphone 5 user, even day time & night time I'm using Wifi to support those apps tools. I also had investigated thru the supporting apple website how to switch off all those cellular usage to support apps. even I switch off all the apps and denied to use cellular, but this data also like water pipe's water flow like never end and running without cease, even I done all the switch off cellular,

Just couple minutes ago, M1 customer service had called me said that for data usage is out of their control. Please assist re-adjust this abnormal running data will incurring unnecessary and outstanding/abnormal cost concerning for all of consumers as well. This is not fair and not reasonable for all the consumers or user to bearing such kind of outstanding or extra unnecessary cost!! and also not fair for consumers when they didn't use of this cellular service for still costing so much!! I'm using wifi to support all those apps operating, how come on cellular portion still incur the running of data usage, even I had shut off all those cellular for each respective apps!!??? & note that this nonsence running of cellular will incur unnecessary cost incurred.

I need the solution or else please assist retrieval back to IOS 7 instead, if this IOS 8 & onward version had brought such kind of inconvenience to all consumers.

Please assist to solve this kind of problem,
