COMPANY REFUSES TO REFUND OR SEND PRODUCT

I ordered a combo of hair from Hair and Bags R Us summing up to R2550 and paid an additional R100 courier fee on the 10th of December 2019. After that I never got any update from them and I kept pestering for an update and was then told on the 17th of December njalo that the hair would be dispatched the following Friday, the 20th of December. I'd told them that I'd be leaving for home that week and they asked me to change the address and said it would then be dispatched the following week.. Because it was a busy time of the year and the said delivery would be on the Christmas week I requested a refund because courier companies are usually unreliable during that time of the year and I'd be traveling so it was going to be hard to say where I'd be at the said time. I was told to wait for 15 working days for them to process the refund.. On the 9th of January I reminded the company that the refund was due. After getting no response I threatened to report them and was told the company doesn't have money to refund me but they have stock at hand. I told them I'd accept the hair but can not wait that 5 days for the order to be processed. Again, they didn't respond. I've been sending messages to no avail. They've stopped reading my texts and are not taking my calls.
