Invoice battle with Telkom

In January 2020 I was called by Mondo consultant to sell two Samsung deals at a price of R219 per month (each). I was glad with the offer and took it, they delivered on agreed date. The problem started when February invoice came, I was expecting R438 plus 198 for activating of both lines which should be R636. To my surprise, the bill shot toR989. I inquired with an email on customer care and they confirmed the prices we agreed on however they still deducted R989 of which I reversed back and sent another email requesting a correct invoice. Today they've sent me March 2020 invoice for R537 instead of R438. I think they're ******** us now. When I'm calling customer care, I waited to be transferred to the next available consultant for more than 30 minutes and I decided to drop the call. Telkom and Mondo, they're looting on us
