Shocking Service!

I ordered online winter clothing for my children through Edgars online services on the 26 April 2020, to date I have not received the delivery thereof. I have compassion for the delays due to COVID19, and am willing to wait for my deliveries, but I have ordered multipal items from other stores online and they have all been able to deliver my parcel on time when they say I will receive it. I have called Edgars numerous times to enquire and each time they say it will be delivered soon. I receive emails to confirm that it has been handed over to the courier and that delivery should be done in a few days, but still nothing. Edgars has sent me a R250 voucher that can be redeemed to say sorry for the delay, when I actually want to redeem it, it says it cant be redeemed- I mean really? I called Edgars again this morning to enquire where the delivery is, to then be told I need to phone the Courier and find out where the parcel is- WHAT?? did I order the parcel from the Courier, or did I order the parcel from Edgars?? I tried phoning the number given, thinking well if Edgars cant give a dam where my order is, or even make the effort to find out where it is, then I will, and no surprise there was no answer on the cell number given - which is also strange- what kind of Courier service do you use that doesn't even have a landline number to contact? Edgars states on their website there is a 3 week delay due to COVID19, But we are heading for the 7th week, and no one knows (or cares) where my delivery is! This is shocking service!
