warning, Data ripp -off from vodacom is real, dont ever take their contracts !!!!!!!

I finally got the wi-fi router after battling with vodacom for 2 weeks to deliver , you are not going to believe this , the nightmare continues, my wifi router was activated on the 9th march , i used it till 1pm when i knock off, this morning when i try to connect i was told that am out of data, how is it possible that 5gb was finished in few hours wheres i was using 2gb for the whole month, i have been using my 100mb since morning it is still not exhausted now at 14:15 and vodacom is giving me some stupid explanation on how my wifi was depleted . i have been using inyternet for years and i also use it for shopping but there is no day that i ever used 1gb . please tell me something better because this is ridiculous, tell you the truth am not going o pay vodacom this time around, this matter is being referred to my legal adviser , i can not pay for something that i dd not use, that i swear with my grave . i thought it was a false rumour that vodacom is robbing people of their data , but i have seen it with my own eyes . vodacom you have messed with the wrong person, i wont sit back and allow you to rob me , i have been your client for years now but i never received such terrible service .
