Refund not received over 4 months

I ordered on their website and paid R2100 on their website on 16 June, after 7 days I enquired about my order which their Manager khaya said theres is a system glitch and I will be refunded on the 27th of June after numerous calls she asked me to email her my banking details the refund will be processed with 7 to 21 days. I have been sending emails and calling they will ignore you the ladies in reception they are always following up and escalating but they never come back with to you. Today its the 23rd of October almost 4 months with no communication . The last time I wrote a review here they disputed it as if they were going to refund me. Their service is pathetic I even stopped doing groceries there at their main store in Roodepoort
