Vodacom do not want my payment.

My debit order failed and I tried calling Vodacom to make a payment arrangement. After going though many options and not of them related to my problem I got though to an operator. After some time she asked me if this was a business account and I said yes. Then she said she has to put me through to another department and then I was cut off. I then searched Google for the business numbers for Vodacom and phoned a few of them but got the engaged tone and could not get through. I when found a WhatsApp number and sent a message but no response.
