False advertising

In April I took out a contract with Telkom. It was the worst decision and one I regret making. I was supposed to get 10 gigs for during the day and 10 for during the night, however it looks as if I am only getting 5 during the day and 5 during the night, that is not the contract i signed up for! Telkom also has the worst service from their call center! I would like out of this contact, the false address advertising and is too much! I would suggest people rather go to other networks and not Telkom
