Ackermans cannot assist with a simple issue

on the 26th March 2015 i purchase an AG mobile Chrome handset as a gift for my daughter, the sales person who helped with the sale, made a copy of my slip and also entered the sale in their registered, on the 9th of july 2015 my daughter decided to make use of her AG mobile only to discover that the touch screen does not work, busy as can be i took the cell phone back to the store of purchase without a slip, i explained to staff member on duty that i do not have a slip but if she could send the phone for repairs and also check the purchase date to which and entry was made in the register upon the purchase, well behold she could not find the store phone register and i was sent home, no effort nothing, now i sit with a phone which does not work, i have been a store manager for many years and in a case like this i will help the customer but surely ackerman staff has no time for that......and they call themselves Phadima
