False advertising

I took out a Telkom mix contract and the device that I was given was and is still advertised as LTE voice and data enabled. <br> I never managed to connect to the lte network and upon contacting Telkom was informed that my device is not compatible with their LTE network. <br> Can you please change my device for something similar which will support your LTE network or do I have to report yourll to asasa for yourll to deliver on what you have advertised and still do advertise. <br> If yourll don't want to assist then please provide me with details of their office of your ceo as stated in your complaints resolution procedure document.
