Vodacom debit order

I took up a cellphone contract with vodacom last year in September to which I'm currently paying 560 every month my account is up to date. Earlier this year in February I took a loan to settle the contract as their installment is too high and called vodacom contact center to pay it off and the consultant advised me to migrates to a cheaper package of R230 a month and I had to pay R2400 told them to debit the money same time to which they didn't and the money was used and had to call them back to let them know to cancel the migration and let me continue with the current package of R560 as the funds are no longer there. I was told it had been sorted out and they did debit R560 on that month and I was told my package was back to normal only to find out the following month they debited R3000 and I called them I was told I would be the difference would be refunded to my account they will take their R560 couple of references was issued to me but nothing happened I had to ask my bank to assist me and had to pay them in cash.. And still continued to call them and another ref no's where issued but still no feed back and yesterday they debited again R3000 and I called them they r telling me to speak to my bank to reverse it and pay cash again.. Unfortunately I have called my bank and was told they can't do the reversal due to lock down I must speak to vodacom... I'm not getting any help with I have other debit orders life policies and insurance waiting to debit... Really frustrated about this situation
