8ta Never fails to disappoint

I have a LTE contract with 8ta, one which i have had since 2013. I recently was charged R350 apparently for an increased spend limit. In 21 months, i have indeed run out of data and phone 8ta and purchased more but now, suddenly, i have a spend limit that kicks in when data is depleted. It has never kicked in before but now does. This is my take, 8ta realizes that they are losing customers because of their incompetence. So the only way to make-up for the loss is to try and siphon money from unsuspecting clients with the hope that no one would find out. Beware South Africans, 8ta is not about providing good service but good *****ing. I have asked to get the settlement amount for my contract and i intend to settle and never ever use 8ta again and hope and pray that people would open their eyes and see 8ta for the ******* that they are and never take out a contract with them, it is not worth the stress. I would rather pay a bit more for Vodacom and know that it is a service provider i can trust!
