Extremely bad service and assistance

Hi i had a bad experience at Game Pinetown, last year around September i bought a tablet from them. I noticed that the bettery life span was not lasting more than 30min after charging but i just said to myself i will take it whenever i have time. Weill 2weeks ago one morning i tryd to charge it and i did not even switch on, i took it to Game @ Westwood and they said i must bring the box as well, which i did bring but i took it to Pinetwon which is the shop i had bought it from. When i got there the lady that was assisting me told me that she can not take it inn because the person who works in that dept. was not at work, he will only be at work in four days time, then i was not happy i requested to see the manager when he came first he told me that i must pay R250 for booking it inn and i must also produce a till slip and i told him i do not have it anymore. he than said if i do not have it he can not be able to help, i must take the tablet and go,what he said i found it to rude and arrogant, I wonder how many people get such a treat ment and i will never buy from that shop again.
