No sense of customer care, contravening the CPA

We visited BT Games Greenstone after being advised to do so in order to return a remote that is still under warranty. Firstly the guys walked past us in the mall, and only returned at 9:10 to come and unlock the store. We were then advised that they cannot do anything for us on a Saturday. Then we were told that the particular model or remote is not stocked anymore, and we need to pay in to get the "newer" version! Who's problem is it that the older one's arent made anymore???? One of the guys' comments was "another one" - so these are clearly useless faulty products!! It then took another 2 days to get feedback!! Thanks for wasting my time & money!
