Vodacom accounts mistake( take 2)

2nd time I'm posting this complaint,No contact from Vodacom.....

I was adversely affected by the Covid-19 pandemic and subsequently could no honour all my commitments, one of which being my Vodacom account. I sent emails and made phone calls to Vodacom to no avail, but Vodacom still tried to take debit order which ended up being unsuccessful. During May I phoned as I was receiving calls daily about the account and on the 19th of May 2020 when I phoned the line was suspended. I was told that they can convert my lines to prepaid and that I would have 6 months to pay the account. On the 24th of May only was my line active again but all airtime from all the lines, which was paid for, was gone. On the 25th of May I settled the account in full for April as well as May and then requested that the contract be reinstated. This took a few days. Last week I noticed and unusually high bill due for May as per the Vodacom app and phoned the accounts department, the lady that assisted wasn’t helpful at all. I waited until the new statement and invoice was emailed to me and noticed that I was billed again for May on the June invoice. This needs to be rectified, May has already been Paid in full. An amount of R2900.87 was paid on 25 May 2020, that was for April 2020(R1487.96) and May 2020(R1311.95) plus admin fees. Please rectify this before the debit order run end of June. The amount of R1741.42 is incorrect and need to be rectified.
