I have been purchasing parts from you for number of years.. As you have 30 days exhange / refund policy.. As you were giving blackfriday deals.. The product difference was in my favour to save some money.. On this occasion I went to exchange The remarks I got back from other members of staff standing around you can be charged handling fee. And exchanged various comments to my consumer rights .. as they made out to be too much paperwork. However I ordered online ordering reservations and the price to pay at the store. Above all I am happy to shop as I was given impression the amount involved was not significant I did managed to exhange.. As far as I was concerned I was within your terms and conditions of contracts..
