Ikhokha ****med me off my R500

I had purchased a machine for my business that had costed R499 at the beginning of October after payment there was no communication just the acknowledgement of payment and no tracking number 2day later a message asking me to upload my documents i tried using different devices but it still would not upload, ive sent an email enquiring about the machine 8days later and still no reply, i went on their Facebook page and asked when am i getting my machine and still no reply i then went on their messenger and that's when they said they will attend to me, i said i would lile to cancel my order as their service is bad after the person has paid they apologised and said they will get back to me soon with the refund process, one of the staff phoned i think it was towards the second week or beginning of third week of November and said my refund will take up to 14 days and today is the 19th day and yet when i message them on Facebook no reply any more and i haven't gotten back my money nor machine nothing, its either they are good to certain client or have begun a new strategy of ****ming people. Please help.
