Vodacom bullying tactics on unauthorized debit orders

I have tried on numerous occasions to be rid of Vodacom. I took out a phone contract and I was paying +/-R1200 . The deal came with free phone & R50 airtime. 2 years later at the end of my contract I cancelled this around Oct Nov 2019 and was penalised for 1 month. Suddenly in Feb 2020 there's deductions from my bank account of R60

I've called on numerous occasions the answers I get on when I signed a R60 contract are all over. One consultant eventually told me this is for the free phone I received two years ago... Vodacom has decided to now deduct R60 airtime for the phone I received 2 years ago. This for a phone I lost ages ago
