a year ago in April,i received a call from one of your sales consultant with regards to the phone on promo that was available that time .He process everything i received the phone but it was not the actual device that i agreed to take . They delivered Mobicel R9 instead of "Iphone 6. When i notice the delivered device was not the one agreed upon , i called the BLUELABEL call centre but they were no answering their calls, Please note that i have been calling for the past 6months with no luck instead money have been debited on my account R350.00 yet the device is not working at qll with the sim that came with the device , I tried to put another network but it still not working . I have been receiving text from BLUELABEL that my account woyld handed over to their legal team .. please attend to this matter . your response would be highly appreciated
