Non Delivery of online purchase and poor customer service

On the 26 November i placed an order online for a DJI Tello, order number # ********** 66, on the 28 November i received a mail that my order was delivered however It was never delivered to me and I contacted the call centre ********** 700, on the 29 November to explained that the order was not delivered and the agent confirmed that a person by the name of Allister had signed for it, but did not confirm the delivery address, I explained that i do not know such a person and how could they not call me, as this was done on the previous 2 deliveries. I was supp**** with a ***. On Monday morning the 3rd December a Thristan from the head office contacted me, confirmed the issue and informed me that this has been escalated to a manager and he would contact me before the end of the day, surprise, surprise - nothing happened. On Tuesday the 4th December by some miracle i was able to reach Tristan on ********** , he explained that the manager had contacted the warehouse and that an new drone would be dispatched and he would contact me before the end of the day to provide me with feedback. Surprise, Surprise, no call nor any comms.

Serveral attempts to contact Tristan on the above number were futile as the phone just rang and when it was answered, she transferred me to the wrong person. I then contacted the call centre ********** 700 on the 6 Decemeber and a lady informed me that she could only escalate the matter to the head office, however she could not let me speak to any managers as they were all busy. Once again i was reassured that i would be contacted before the end of the current business day. Yet again, that was met with the Incredible way, no call.

On 7th December, I was contacted by Andile, a lady who once again requested me to validate the issue, once this was done, she asked me to confirm if the item was delivered, when i indicated in the negative, she informed me that the issue was escalated to a manager and that she was calling to confirm delivery, however she did not know about the issue. Once again i was told that she would follow up and she would come back to me, hence again no return call.

During this time i logged a supplementary complaint on the Incredile Connection website portal, once again the chat agent could only escalate. I had 2 conversations on this site, of which i have the screenshots and promises of calls the same day were met with the Incredible Connection customer service, NOTHING.

I once again contacted the call centre ********** 700, on the 10 December and chatted to Shantani, explained the issues to her, supp**** her with the ref numbers, and once again was told that she would escalate this to the head office and i would be called before the end of the day by a manager,

I would appreciate senior management intervention as how many other online purchase have not been delivered?
