Delivery not on time.

Emailed them on Friday regarding getting my waybill to track my order. Didn't get a reply back , I then decided to call them no one answered. Today I sent the firm email asking for my waybill details. I received a reply within 5 minutes saying they will follow up with the courier company ( they have yet been able to give me a waybill ) sent them another email asking for the waybill again , no reply on the email. sent this email almost 2 hours ago. I am a returning costumer and their service is complete garbage now. Hope they sort their service issue ASAP
