I am absolutely fuming about my order...

I am absolutely beyond ****ed off at this point! I ordered an air cooler from them online for collection on Friday, 23rd of February 2024 and then a lady contacted me on the Sunday 2 days later that they had one in stock, however it was faulty and they needed to source a new one for me and it should be there by the following day so they asked if I wanted to cancel my order or wait and I said it's okay I will wait. The Monday comes around and I hear absolutely nothing so I decided to wait till the Tuesday and see if I hear anything and still nothing. So now I have to waste my airtime to get a hold of them which took about 3 tries to finally get through to them just for them to say that the truck never delivered my order on Monday and they will call me when it does arrive... In the process I had already tried to contact them on their WhatsApp number which I still haven't gotten a response on till this day, I've emailed them and still haven't gotten anything back and I even messaged them personally on Facebook instead of complaining. I literally had to send question marks to finally get somebody to respond and somebody finally did and called me saying that they will call the shop that I ordered from to find out what's happening and from there I just haven't hear anything back. So I messaged them again on Facebook to ask what's happening and haven't heard anything at all just to wake up this morning and see that they read my message they just didn't even bother to respond... Absolutely careless and terrible service from them!
