Unprofessional Service from Mr. D Courier

I have been waiting for my credit card for more than 5 days since the first SMS from fnb that within 48 hours Mr D. couriers will contact me. Their call centre is not operational you'll hold the line forever without getting any help. They sent sms that they failed to contact me whereas no any missed call I have ever received from them.The worst courier service I have ever met. As to FNB how it came about to award this useless company a contract leaves much to be desired.
