Debit order Woes 2.0

Second take.

My debit order was always on the 1st of every month, but due to my payment date that changed, I changed it to the 7th of each month.

So first my account was debited on the 2nd of May for the outstanding balance, and when the 7th of May arrived, Vodacom tried to debit my account again. This debit order did not go through as it was not arranged, my account is up to date, and all that. I was charged for the debit order and I received a credit note from Vodacom.

Now today, I receive an email that my account is overdue and I need to make payment.....

This is not true, as my next payment date is the 7th of June 2025. When I phoned Vodacom collections with regards to this, It was stated that on the 7th of June 2 debit orders will go off my account.

So now Vodacom wants to bill me for 1 extra month i.e 2 months subscriptions in 1 month.

My account has never been in arrears, all that changed was my debit order date, nothing else changed. There are no extra invoices on my statement.

I'm really upset with this bad and sly on the part of Vodacom, as I was billed on the 1st of May 2025, and this payment will be on the 7th of June 2025, so where does the extra payment now come from.
