Refund of suitcases

On 18 December 2018 I bought a set of suitcases from this Company the order no was:ORD410990 . It was delivered on the 19th. The Courier company was Bex who then contracted it out to Parcelninja. On opening the box which was damaged I saw that the suitcase in which all the other suitcases fit in, was damaged. I phoned Bex. They said they would handle it and give me feedback. I never got any feedback. I had to go and buy another suitcase, because I left on holiday to Europe on the 23rd of December. I reported it to Hyperli on the 23rd aand asked for a refund. I have sent numerous queries. They said they cannot refund me and that I will be given a voucher, which I still did not receive, nor the R1400.00. That is what I paid for these suitcases. I have dealt with Hyperli before and have never had a problem They have no contact no so how do i get my money back?The ticket no that they have for my query is 282475. There is also Refund ticket id which they have given me, but still no refund or reply to my request. pleas can you help me.
