No refund

Makro owes me R1,634.00 My order was placed on 29 Apr. On 12 May I got an email stating that I will be credited within 7 days. On 20 May I phoned the Call Centre and was told that they will investigate on why I have not yet received a credit. On 5 June I sent an email, but did not receive a response. On 9 June I phoned the Macro Call Centre at 14:45. I was in the queue for 15 minutes. Eventually somebody answered, but the line kept dropping and I could not hear anything the call centre agent was saying. I left a message on Facebook messenger, left a support message on Makro’s website, and sent emails to Makro Care, Macro Customer Service, Customer Services team. On 11 June I received a message that I will be refunded. On 25 June I followed up with an email, but have not yet received a response.
