poor service

On Saturday 2016-01-31 I went to cash crusaders to buy a tablet for my son. I got the tablet paid and I was given receipt and the person who was assisting me told me that it had a 6 months warranty. on Sunday I tripped and the tablet was in my hand and the screen cracked. on Monday I took it back because I was told of the warranty. when I got to the shop I was told that it cannot be fixed because the lcd was an exclusion. And they forgot to stamp my receipt with a stamp that had exclusions. After the lady who was helping me acknowledged that they made a mistake by not stamping the receipt and informing me about the exclusions they still refused to take it in for repairs. as a customer I was supposed to be told Wat the warranty entailed. I want the tablet to be fixed or given my money back. It is not my fault that the receipt was not stamped and I was not negligent in any way. They should have done their job properly.<br>
