Lizam from foneyam is very rude

I received a call from Lizam from foneyam that rude person must NEVER EVER call my phone again. I need someone to take accountability for malfunctioning phone that I took from foneyam. From day 1 the phone was a s**** and the manager from Ackerman's in Palm Springs is well aware of the s**** they sold me. I took this phone back and I was told I would need to pay R1500 to cancel a contract does that make sense that I must accept a faulty device. Now I am sick and I am receiving calls from rude Lizam telling me I owe a rental device tell her to come and pick up this s**** device since she knows best.
