<p>I bought cellphone from( store code 0522) CNA Clearwater, Hendrik Potgieter & Christian De wit date 21/12/2016,(Hisense F20 Gold was on display) transaction no. 055244. On the 28 th of march my battery went flat anf tried to charged it when got home. it couldnt charge and turn on instead went very hot like was gonna pick on fire. I took it to CNA on the 29/ 03/2017 in the morning. Around 13h00 same day i received a *** from ********** 334 (repair centre)confirming the receipt of Cell phone. I went back after 2 weeks to check with CNA and the lady name Cherity (from cellphone department )confirmed that its was pick up on the 29/03/2017 and will take 21 days. I have phoned them 2 times and went there 3 times and no communication about my cellphone. i have phone again today (04/05/2017) spoke to CNA branch manager and he refered me to Lawrence one of his Junior. Lawrence called me back with different story saying my phone only left the CNA on the 19/04/2017 for repair still at repair centre. I told him to check when my phone will be ready not to check on the system ,he must call the repair centre or give me the number to call. He promised to call me back in a hour . Now is more than 5 hours and hastnt receive a call. all i want is a new phone if that one cannot be fixed . NO CUMMINICATION.</p>
