UTTER POOR SERVICE PROVIDER

I have received a phone contract last year of a phone that was broken. The agents never came to fetch it on numerous times. Up until this year in September when they came to fetch it, realizing it is broken. They supp**** me with another phone but up until now they have never corrected my ITC leaving me with a bill to pay for almost R8000. Is this fair to pay for a broken phone. Not seeing their mistake. I am done with incompetence and will make sure that all on social media will know who this company is. Because of this listing i am unable to find employment and able to feed my family. Not seeing their mistakes.
