Day light *******, this company should be shut down

This network has really made me suffer for the past two months after being a patriotic customer constantly referring others .. I have referred my whole company to use this network and here I am getting ******.. I have been charged over R10k for out of data bundle usage even though I have a credit limit and I have not even used my data bundles .. Even after paying these crazy amounts for their technical mess ups and poor system delivery they still blocked my sim completely .. i run my business through my phone and this is my livelyhood. I am a very patient and understand person but this has just become ridiculous .. Can't even blame the call centre agents as they are always sorry and can't do anything about it !! Even they agree that this is ethically wrong and there's nothing they can do besides apologize and watch this ******* take place !!
