Refund or Delivery of items paid for!!!

On the 27 of February 2020, I ordered 70 x JBL Tune 500BT Headphones through George & Noni & My Digital Store. Full payment was made to them on the 6th of March 2020 for an amount of R48 685.00. On the 11th of March 2020, I followed up on delivery & was told that there was a backlog on JBL's side and they would receive stock on the 16th of March. On the 24th of March 2020, I was informed that they still had not received the stock and then the country went into lockdown from the 26th of March. On the 1st of June 2020, I contacted Noni re: the order & was informed that they had not received the stock from JBL, but that they would receive the stock by the 26th of June. On the 29th of June, I sent a follow-up mail to Noni to query the order, but no response has been received as yet. I have tried calling the landline number - ***, but the number is engaged. I have also tried calling George the manager on his cell - ***, but he doesn't answer his phone. I urgently need to take delivery of these items and must say that I'm appalled by the fact that full money has been paid, but the goods have not been received & no-one has had the decency to get back to me with the status of the order.
