I bought a BOSCH cordless vacuum cleaner on 27 December 2017 from John Lewis in Croydon. When I bought the item I was told by the sales assistant that the vacuum would last an hour before it needed charging again. I considered a more expensive model but was told that I would only really need that if I have any pets and I don'y. Unfortunately this is not my experience and my vacuum doesn't last longer than about 20/25 minutes before I have to recharge it for several hours. This is extremely inconvenient and so I returned to the John Lewis store today to complain about this.. The first sales assistant I spoke to agreed that there must be something wrong with the vacuum. He checked the internet and confirmed that the charge should last one hour and then directed me to Customer Services. Customer Services needed to test the vacuum and indeed it ran out of charge after 16 minutes in the store. (I had already used the vacuum for about 8 minutes that morning.) Once it ran out of charge Customer Service staff then came out with various excuses - this vacuum is only suitable for an apartment, this vacuum will only last 25 minutes on the middle power, this vacuum was only suitable for occasional use etc. I was questioned as to why I didn't bring the vacuum back earlier and was made to feel that I was in the wrong. Customer Services staff also disagreed with my view that John Lewis was misselling the product as I was quite clearly told that the charge would last for 60 minutes. I certainly wasn't told that the vacuum was only suitable for occasional use in flats or apartments! I am extremely unhappy with the way I was treated by Customer Service staff today and I would like this situation resolved as soon as possible. I cannot believe the attitude of the staff. I have always chosen to shop at John Lewis over other stores as I believed a customer would be treated fairly and reasonably by John Lewis should they need to return an item. This was not my experience today and it will certainly mean that I no longer chose John Lewis as my preferred place to shop.
