Poor Service

I bought a microwave online on the 15th of December 2022, only to find out that it's too big so I decided to return it n swap with a smaller size. I logged a return and got a response that it will be collected on the 19th of December 2022. I was OK with that but then no one picked it up and no one bothered to call or email. I was very disappointed. On the 20th of December 2022 I decided to take it back myself and requested a full refund. I was told that it will be in my account within seven days but I still haven't received anything. I JUST WANT MY MONEY BACK AND WILL NEVER BUY AT MAKRO AGAIN. YOU HAVE POOR CUSTOMER SERVICES. I have already called twice, the 23rd and today again.. They make me hold for more than 10 mins to query and another 10 mins holding to get a lousy feedback of escalation. I am so sick of the treatment and I am done with MAKRO
