Telefunken Home theatre

i bought a home theatre from game westgate last year september and since lost my receipt.<br> i took the unit to the supplier in may and was advised that i will have to produce a receipt and then told them i dont have it they then advised me to call the call centre and ask for all my receipts which didnt happen. i then went back in july and there was no help still, i then went back again in october after getting my bills from the call centre only to be told that they cant help me as my unit is out of warranty i will have to pay for the unit to be fixed after going to game three or four times they didnt even take the serial number to check on their system what is the status of the unit. i dont understand how i could buy a unit from game and they dont have it on the system that is just poor service as they where not even willing to assist me with the problem.
