NO RESPONSE, NO PROGRESS, NO RESULT!

Once again I revert back to this method in an ATTEMPT to get a response. First of all your billing system has some serious technical issues - based on the initial change by someone in your company that changed/removed my monthly data allocation unbeknown to me resulting in exorbitant unbilled calls since March. Secondly, your call center, \online specialist"and enquiries team's lack of response let alone assistance in helping to resolve issues. My unbilled amounts for 2 data events on the 30/05/2015 at 1:10AM for over a Gigabyte of data and 3:10AM for 96MB respectively are RIDICULOUS!! First of all I was most definitely asleep at this time of the morning"
