Incredible Connection gives zero customer service

I have to date experienced unbelievably bad customer service from Incredible Connection. I ordered a relative expensive item (R4000) from their website on Wednesday 22 July 2020. On Thursday 23 July I received an sms that the parcel has been handed over to their couriers, RTT Logistics. A tracking number is provided, but on RTT's site it says that no tracking information is available. After not receiving the item, or any further updates, I called the Incredible Connection call center. After a ten minute wait the call was dropped. I again called and left a message for them to return my call - as per the instruction of their system. Nobody phoned. I have since sent 3 emails to the email address they provided, and since Tuesday I have not had a single response. Call center is still not picking up calls. Left a message on their Facebook page, to which they instructed me to "inbox them"... which I have done... also with no response in the 2 days since messaging them. I am R4000 out of pocket, without the product I paid for and urgently need, and clearly dealing with a company that does not want to engage with its customers. They will NEVER EVER see any form of business from me again. I just hope that I will be refunded.
