Liers and False Promises

After saying that I desperately need my parts after I had paid by the next day I was advised by Jacqueline the Customer Service Rep that my parts would be delivered the next day on email. I started to get worried that the parts would not come as it was already 3pm so I called multiple times and the lady that answered put me through to a bot numerous times and when I try call at least 6 times i immediately go through to the bot no one answered then I couldnt get through to them at all...I got an email back and it said it will only be delivered on Monday but Jacqueline email said it would arrive the next day. They claim that they deliver same day within 25km that is a lie! i emailed Sales I emailed orders not even an apology. I call and call the whatsapp i send messages nothing only Saturday be told the parts are not ready. i am disgusted with this service and lack of feedback. I dont even have faith that the correct parts will come even if they come. Now I cannot start my new job on Monday because of these liers. what am i going to tell my boss!!!!! there goes my job!!!
