Pathetically Defective Acer Liquid Stupid Phone

In 2014 I purchased a new Acer liquid Z150 phone at Markham in Sammy Marks square in Pretoria. The cell phone operating system suddenly crashed and upon restarting it was frozen on the boot/reboot Acer logo screen. I thereafter took the cell phone for repair. It was collected at the Markham retail store at the Sammy Marks square in Pretoria for delivery to Incredible Solutions premises in Sandton. A week later I received a call from a very rude technician. Thereafter the cell phone took ages to fix for just a simple problem on a brand new phone. I received the cell phone in January 2015. After about 12 hours the phone froze again. I then took the cell phone back again. A week later I got a call from Markham informing about the arrival of the phone. Upon receipt of the phone it failed to boot. It froze again after about just 1 hour. I then decided I would try the cell phone for about a week.On Friday the 27th February this pathetic product froze again for about 22 hours, a disgustingly disappointing occurrence indeed. At this stage the only acceptable solution to me is REPLACEMENT of this ridiculous product, or much more fairly a REFUND.
