BAD CUSTOMER SERVICE FROM MAKRO ONLINE STORE

i bought a fridge from Makro online on the 24th of February, 26th February received a notification that it was dispatched. I waited for the delivery until 31 March 2023 cause they were following up with the courier everytime i call them. I then asked for a refund which i have not received till today instead i am wasting my airtime only to be told that the refund amount exceeded the float and the matter is escalated to the team leader to follow it up.
