Terrible customer service

I placed an order online on the 12th of August 2020 and it was supposed to be delivered to me within 5 - 7 days as per their policy but up until today I haven't received it and nobody is bothering to say anything to me about my delaying order. I emailed them numerous times and they promised to follow up on the matter and get back to me, last I emailed and called they promised to call me back once they spoke with the courier company they didn't get back to me and they are now not responding to my emails. I called the couriers, they sent me from pillar to post, lastly they told me my parcel was lost. Of which I don't know if it true or not, I then called yde that confirmed it that I was lost and promised to call me with the complete information how are they going to replace my order. Fortunately when I called I spoke to the same person whom I was communicating with via email regarding this issue and ended up ignoring my emails Nureesa Gribble, she apologized and promised to get back to me within 5 minutes of which she never did. Right now I do not what to do because the company I trusted is now avoided to attend to my complain. My Order number 803002P800 is and tracking number is =PNJ***5 courier company is parcel ninja. I must say yde and parcel ninja service is very terrible
