Most pathetic service: Sleepnet milnerton

I paid for a mask at the Milnerton branch including overnight delivery. I had to follow up numerous times and after 3 weeks got an email that the mask is ready for pick up. I send numerous emails to inform them that they need to send it via overnight courier as that is what i paid for. Yet , no response. I called 10 times and never once could i get hold of them as nobody picks up. This is the most pathetic branch of this business i have come accross. They are unprofessional and I would recommend to avaoid them and rather go to another branch.
