Owing money in the first 8 days of subscription when 1st sub is paid???

I ordered and paid for a fridge on 24 November 2023. What I didn't realize, was that I accidentally ordered 2 fridges.

Support emailed me to advise me of the error, which they said they would rectify. I later enquired about the overpaid amount, which I was advised would be used for the next month's subs. However, the overpaid amount was refunded to my account late December.

The item's delivery was due to be within 14 days. However, when not having heard from a courier by the end of the 14 days, I followed up. I was advised that they did not have enough stock and that a courier will contact me once stock is available.

The fridge eventually arrived on 20 December.

To my knowledge, and as their website advises, the first payment would be for the first month from when delivery has taken place.

I now received an email on 28 December, stating that my subscription is being cancelled as I have an overdue payment. Rentoza never attempted to debit my account with another month's subs in December. The funds were available should they have tried, anyway.

For the last two days, I have been trying to correspond via emails in which I have been advised that I owe them money and that my sub is being cancelled and they will collect my fridge. I have also sent a WhatsApp (as they advise this is what needs to be done when you try to call them). NO ONE IS RECTIFYING THE ISSUE!!!!!!!!

I have requested to be called back, as the back and forth emailing is just not solving the issue but I am receiving NO joy.
