Back and forth claim

I have a bad experience with abacus, I submitted a claim, fair enough I got a message and an email that the claim has been approved and I need to go to the store to collect the device, when I get to the store they don't want to help me claiming that they didn't receive anything from Abacus they called and spoke ko Kgaugelo and he advised that he will fix the reference and send it to the store in the morning, when I went to the store the next day in the afternoon I was turned back again and they claim that still nothing received from Abacus and they call again and I was told that they still fixing it. I'm so disappointed that I had to leave work early and go to HiFi corporation for nothing. The service between HiFi corporations and Abacus really is bad
