trying to find parcel, call centre doesnt answer

I have a speed services parcel that I need for business. Its been sitting at the Jhbnet for 2 days now despite paying for counter to counter overnight. No one answers at the call centre and I just held on for an hour and a half. The tracking cell number doesnt work. How is this good customer service? This is affecting my business. Please contact me so I can get my parcel. I have also emailed you but no reply, no surprise there!
