Offered me a contract, only to go back on their word and now they've disconnected my service!

I've been on the LTE uncapped for almost 2 years now. On the 30th of November I received a phone call from telkom asking me if I wanted to upgrade. The same package, but no FUP and I get a LIT box. I agreed. When I contacted telkom they said it was a **** and knew nothing about it. I did some digging to find out that the people who phoned me were SellDirect. A sales agent of telkom. Telkom finally confirmed this, but then they started negating on the deal, telling me that I have to pay more but that there still is a FUP. Now it reached the point that my LTE has been de-activated, while people are scurrying around trying to protect their own asses. I have cancelled all debit orders with Telkom and will not be paying them for anything.Thanks I can do a lot with the extra R800 a month
