Worse online service ever!

I bought a dress on the 5th of November 2020 while I was in Oudtshoorn. I wanted to wear the dress to a funeral that was on the 14th of November. However, I only got a sms notification today that I can collect. Firstly it took TFG more than 2weeks to deliver, and I made it clear from the beginning that I will not be in Oudtshoorn for long... so now TFG (Facebook) response is that I have to wait for the package to be returned to the warehouse and cancelled which could take up to 8days or I must cancel the order... Really guys, do you know the meaning of "online shopping"???? For some of us online shopping means convenience and efficiency... which you have no clue off!!! I will never buy from you ever again and I will also make sure that my friends and family knows about this bad service.
