Customer service

Hi I am such an unhappy client of netstar Had my unit for 4 years almost. I need to upgrade my unit and the service I got from them is unbelievable, those consultants are so unprofessional the so called manager Aba Baker acted as if he couldn't hear me and drop the call, he said he will call me back and never did. BARRY SICETSHA USELESS NO MANNERS TEAM LEADER has no client service ethics, Eunice in retention didn't call me back as she had to, Onismus Rammuela tried but also doesn't understand how his systems work. Lerato has no manners at all. I requested call recordings and non received thus far, my unit need to be upgraded I have been struggling since last year. Last week I called the lady sent a contract and up until today have not received no response from a technician to do the fitment instead they lie to you and say they done the referral, when I requested for the emails they only sent it yesterday since last week Quick to debit but can't deliver I am still paying for a unit that doesn't work, how do u explain that. U sent emails to customer service they dont come back to u. I asked to cancel my contract also still now nothing received. I had it with this company honestly, I need this sorted out they need to deal with their *********** staff and train them ASAP if they want to retain their current customers.
