Horrible customer service and experience

I placed an order online on the 14th of June. Had to make endless calls and send emails with no response to the call Centre. Ultimately after writing a review on this platform I received a response where I was promised that since my order had to be canceled due to unavailability of stock I would get my full refund of the money that I paid for my order which was R779. 00 to my surprise today I woke up. To a notification and only R499. 00 was paid. Where is the rest of my money. I haven't ordered anything more and I will not be receiving anything from poetry. Where is my money guys ?
