Replace item purchased unrepairable

i purchased a number of items from the store in march 2015 and returned a dvd player for repair 5 weeks ago i had no feedback and went to the store on sunday for the second time taking in the remote and power cable as requested. i had full details of the transaction invoice number etc unfortunately the original invoice had been mislaid. the manufacturer had agreed that the machine could be replaced but despite having the details and date of the transaction the store refused to assist. whilst i do not expect any feedback or response i will not be purchasing any further items from your company going forward and although i am only 1 customer i will not recommend that anyone purchase from yourselves. it does appear that you are willing to take the money but when there are issues really are not in a position to provide any service
