Non existing after service

my contract was coming to an end I then took the special for a rooter with 1TB, for R 399 per month, I then took out a smaller contract for R 150 airtime at R 135, making it R 534 per month. The person I dealt with promised me on the phone and did say the call had been recorded, LEROY SILINDA said his direct number is ***, which is a lie, he said it would not be more than R 534 per month and if It is you can call me directly, well guess what I have called directly, and that is not his direct number, he doesn't have a direct number. So my bill is more than a R 1000. I have called 7 times and no one at Vodacom can resolve this
