VOADCOM CUSTOMER CARE STINKS!!!!

I am writing on behalf of my husband who has a Vodacom contract. I have sent many emails to which I have had NO response!!! have made many phone calls, to which there is still NO solution. He has been getting a statements dated the beginning of the month and payment due the begin of the following month eg. statement dated 03/07/20 and the debit order was deducted on the 03/08/20, suddenly there was a deduction on the 18/08 as well. He then received a statement dated 01/09/20, due for payment 18/09/20. At my last phone call, I was re-assured that the debit order is for begin Oct, and exactly I knew what would happen, the debit order had come off today 19/09/20, which did not go through, due to lack of funds, now I am going to be charged extra bank fees due to their lack of correspondence/communication. Which I will fight to get refunded . I am absolutely sick and tired of people who are not doing their job proper and giving the properly Customer Care. What has happened to Vodacom. I don't have the time to spend on the phone or computer, fighting for what I have paid for. Who gave them the right to change the date of the debit order?? Now they will contact him, cause he now 'owes' the money. If this is not sorted out soon, my husband will be cancelling his 'contract'. He had popped into the outlet in Blue Route, only to stand there for 1/2 hr without getting any service, cause their consultants are minimal.
