Afrox... Again...

After having to resort to this platform to get service, here we are again... Clearly a problem with ineffective staff. I called on the 23rd of July 2020 to have the machine collected as my Mom passed away. They collected it on the 24th of July 2020. I emailed the collection note through to customer service. Yesterday a lady calls about payment, and I ask her to please send me the credit note for the 8 days and I will effect payment immediately. No credit note was received, and last night the full amount was debited from my account. Can anyone at Afrox do the right thing without a fight?
