customer service

I took out a 24 month contract with glocell. I received the handset without the sim card.I tried calling them but was put on hold for extended periods of time (however when I selected the "new contract/upgrade" option my call was promptly answered, but they transfer ed me and I got put on hold again) I then messaged glocell via their website outlining my challenge. I received a prompt response from them saying that due to high call volumes they are unable to take my call, however a consultant will be in touch with me. This was on thursday 28 April 2016 at 4:36pm. To date I have had no response from Glocell.... call volumes must be very high :-)
