Extremely pathetic aaaaargh

Their service is pathetic. I paid them for my deliver it’s been three weeks now still nothing, been calling them timeously calls gets cut sent numerous emails there’s been no response tried reaching out to them in all the media platforms still nothing as it stands I don’t even know what’s happening with my order. Their joke of a whatsapp number you never get a response there I hate dealing with such I don’t know how they still in business.
