********** debit orders

There has been a ********** debit order going from our Business Account for the last 3 months, we have send numerous emails for numerous email addresses that's been given to us from the 5th of November 2018. The response from Vodacom has been very poor, eventually after 3 weeks of getting no where I received a response from the correct account manager. I followed the steps he gave me to allocate this debit order to the correct company this was done on the 28th of November 2018, from that date I have not received any response from Vodacom and the debit order was debited from our account AGAIN. Vodacom now owes us R2574.48 in total. I called the account manager Yesterday and he said he will follow up how far this request is and I must call him this morning, I called 6 times and there's no answer, I also send an email and received no reply. Please keep in mind when phoning Vodacom everytime the call was no less than 25 minutes. We need feedback and a refund as soon as possible or this matter will be taken further.
