Pathetic service

I ordered a smart device and have been informed that I could expect delivery within 3 working days. On the third day I contacted the smart device department to enquire on expected delivery of my device and no reason could be supp**** as to what's causing the delay. The consultant informed me that the matter will be escalated to a manager and that I will be contacted to provide me with an update of the status of the delivery. I have also requested the manager to contact me as he was not available. I am yet to receive any feedback. Since I have contacted the smart device department twice without any satisfactory service or outcome on the delivery of my device. I've also left numerous messages to be called by a consultant and not once have there been any response to my requests. It's now 5 working days since my order was placed and approved and I am yet to receive my smart device. The consultants are absolute clueless and useless. Extremely poor service to say the least. Highly frustrated with FNB.
