No answer on my refund

On 21 April 2019 I bought 3 bar stools from Decofurn Centurion. When they brought out the stock from the store the stock were as follow: 1x Broken and base baldy damaged, 1x Cracked and base badly damaged, 1x Plastic not smooth and will hook your clothing they brought out another stool and on this one paint has run. I requested a refund where I was informed they don't do refunds if paid with debit card and that head office will process refund. I filled out the requested forms and left. On 25 April 2019 I phoned head office to followup on the progress of my refund. They said I should speak to the branch I bought it from but they will log a call for me and send a confirmation email. On 26 April 2019 no email and no call. I phoned the Centurion branch and they have no clue of my paperwork for the refund. Emailed the paperwork to them . I received a call from the branch 5 times but the lady could not hear me and tried to phone back twice and still she could not hear. Later the manager rep**** that my paperwork is at the accounts department and my refund will be processed over the weekend. And another mail that they are busy repairing the phones. On 30 April 2019 still no refund and emailed the manager again. I have missed the call from decofurn and phoned the manager back. He will check the progress and let me know. 01/05/2019 decofurn called but I missed the call by a few minutes and phoned back leaving a message for the manager as he is not available to talk. No call back within 1 & half hour so I tried to phone back 2 times again and sending a mail. 02/05/2019 09H45 still no call, no email and NO REFUND. Phoned again to speak to the manager but now its a different manager and he said my paperwork is at head office and they make payments usually Tuesdays of Thursdays but he didn't even take my details so I don't know how he knows who's refund it is he is talking about. Then he rep**** the person who would know the answer is only back tomorrow 03/05/2019.

I am tired of wasting my time and money on them. My airtime, my bank charges and my loss for waiting so long for my money.

Very poor service.
