Worst Customer Service in South African in E-Commerce

After ordering online on the 11th of April, I the item was not an essential service to be delivered but it is on sale online and I wonder why would you make an item on sale but can't deliver.

Till date, no communication from Incredible connection and the Consumer Service chat has nothing to say besides we will escalate to head office and a reference will be sent to you,after spending an hour waiting to talk to someone

It is sad that South African retailers are the worst of it kind and I have learned a valuable lesson from buying online and from Incredible connection
