Telkom ****s contract customers with their lies!

I took out a contract with Telkom in 2017, and subsequently renewed it in 2019, now in 2020 I'm informed that the data I've been receiving since the inception of my contract was erroneously credited. I took out the contact because it said I was to be offered 10 gig day time and 10 gig night surfer, now after receiving the night surfer and not day time data, I enquired and was told that I was actually supposed to receive the deal for 3 months then I'd get 1 gig monthly for the period of the contract. Problem is, that's not what I agreed to.. And if it was why did it take them 2 and a half years to figure out that something is wrong? And if it's so wrong, why did I get the 10 gig night surfer? And also whose fault is it that I the customer was not informed about this in the store prior to signing the renewal contract? This is totally unacceptable and Telkom is taking its customers for fools because when I enquire from them through various social media platforms I get no response yet their lines are forever jammed.. TELKOM is not transparent in their dealings with customers and they are ******** people for their hard earned money be a they know that if they explain all the terms and conditions up front no one will take out a contract with them after...
