R40 Uncapped data

I am a loyal customer to MTN service provider. since MTN has been having issue with their network the MTN uncapped bundle has just been a *******. I have been using uncapped for some time and never experienced such issues. you load the data and it clearly sates that you will be connect for 24hours, i know that if you rich 110MB the speed gets throttled. recently you connect and with in 12-15hrs you get disconnect and get the message \you have run out of funds please recharge"and you will not even get the google page. on the 3rd of June 2015 at 16:30 i recharged with the uncapped bundle... immediately that page showed without even connecting to google."
