Blocking of Internet

On sunday night 29 March 2015, my wife received a message on her laptop via Wi-Fi, that the internet is blocked because we have exceeded our data limit. I am on uncapped, 4MB line. On Monday I checked my computer which is directly coupled to the modem, but no messages. My internet however is totally blocked, in such a way that I can not even download my e-mail, or access facebook for that matter. Now I cant understand if I am on uncapped, how could I ever have misused the date on my computer which was switched off at that stage. Secondly, how can they block my internet without any messages or warning.<br> During December 2014, I had the same problem. At the Telkom offices they saw that I am paying for uncapped, but is only on 20GB capped. they rectified it and I did not even claimed the extra money paid over the six months that they changed me to 20GB capped.. If you try and phone the complaints number 10210,<br> they explain to you about unprotected industrial actions and that it will be difficult to answer your calls. I am without internet now and everything together with it for three day now and still battles to reach Telkom. After all the adverts and promises, this is pathetic servic
