Advertised one thing, given another!!!!

After a whole 3 and a half weeks of waiting for my delivery from telkom, they give me the wrong amount of data?with my router. I initially ordered the Octobers double data deal 20gigs day & 20gigs night and in turn got 10gigs night time and 5 gigs daytime, I honestly want to know if this ****ing network takes me for an asshole because im PAYING for something and not recieving it. Is it my fault that their delievery came in the middle of the month??? So u expect me to recieve pro rata??? Am I an idiot. Nobody said the delivery needed to be delayed. That was your fault... plus customer services cant even send me a copy of my contract they need to track down the person that assisted me with it in the beginning to set up the contract... WHAT BULL****. If its pro rata believe me I will throw it through the window of the store and wont pay for it. This is ridiculous. This service is pathetic... Gosh I dont deserve this for paying salaries of workers. So I need to see some improvement and way yourl going to make it up to me or I will take this further than this platform.
