Refund ****

I purchased the Russell Hobbs breakfast pack last year but the kettle stopped working, I returned it to makro centurion, it took them 2months to respond, asking that I bring in the kettle back in store for evaluation, later received a call to bring in the toaster as well for a refund. I did that on the 5th September 2021 a d was promised the refund back into my account within 7days.its the 30th today, after all the emails I've sent and several calls I made all they tell me is "they have escalated" how much more of my data and airtime will it take for me to get my money back? I've resent my bank account information incase your systems are unable to pick up which card was used. No communication at all from makro, I have to constantly call every after 3rd day. ***
