"Sainsbury's stonewalled my complaint." I made an enquiry both in store and by telephone about getting a replacement for a defective cooking pan which came with a 10 year guarantee. I have all the packaging but no receipt and cannot recall when I bought it. I was told that since the product line is now discontinued and I don't have a receipt there's nothing they can do. Can do or will do? I said I would accept a similar pan from another line. Still nothing they can (will) do. I asked to speak to somebody higher up. No point - nobody will give any other answer. Called another number under 'How to make a complaint'. Clerk took my details, gave me reference number. I asked what happens next. A manager will look at it. Will they write to me about it? They might do. No information about timescales Searched online but cannot find anything about Sainsbury's Customer Complaints Handling Procedure. Stonewalling and making no effort to satisfy the customer is bad customer service. First time I've experience such a response from a business of the size and reputation as Sainsbury's. Won't be shopping here again.
