Telkom full of nonsense

Be very careful of telkom. Lately they are charging me for a deal on my contract I never asked for. I've always had a 20gig data deal with telkom (since 2016) and have never had any issues. Last month and this month though I am neing charged an extra 350 bucks for a 10 gig deal I never asked for. All of a sudden my data only sim has minutes and other stuff I never asked for.
