Angry and frustrated customer

I regret ever taking a phone via Hi store Maponya mall through Payjoy, I have never seen such ****pier service in my whole life,*********** agents and sales consultants at the so called store in Maponya,. I have never heard of a phone motherboard being removed if a phone is blocked which by the way only needs a factory reset. I would like to have my 30% back which I'm told by the store that I cannot have it and when speaking to an agent of Payjoy via the call centre they tell me to go back to the store so that they can see if they can do a refund. I used this phone for 4days and the finger print was not working for all I know I was sold a mulfunctioning phone coz after restarting it was not taking my password which by the way is shocking coz I always use same passwords for all my personal things and it is not the 1st time iam using a finger print phone. I did not use the phone for even 7days and I have have tossed back and forth as if Iam not using my time and transport money to go to your stupid store who will refund that money,because the consultants there don't know how to assist me,but all I get from Payjoy is a. Sms that iam owing you for what when the phone is not even with me but it is supposingly at the store or your headoffice. I have never seen such an *********** store and it's headoffice before I asked the agent I was talking to to ask her Manager to call me yesterday already as she was in a so called meeting but to this day no 1has called me back. I would like to get my money so that I can go and get a phone that works somewhere else were they know how to treat a customer. Instead of being told I need to apy again for your technicians to fix a phone that is not broken but just needs a reset. Never have I seen this for a phone to be reset it takes you guys a month never ever have I seen this.
