Complain to ASDA, don't they usually give something back for your troubles?
Recently I've had to return two items to ASDA. A piece of plastic resembling the cross section of a hosepipe about a centimetre in length and breadth in a third party Haggis which I only discovered when it was in my mouth,and a piece of grit, more like quartz in their own Muesli.
In both instances I was given an immediate refund (against the receipt) at the customer services desk.
I then received letters from Head Office stating they would investigate and I should receive a reply within 28 days (might have been 30).
In the case of the Haggis I didn't hear anything from ASDA within the specified time frame. I phoned them (free phone number), they said they were still waiting for a reply from the third party. I then had to remind ASDA that they had said they would reply within a time frame and that surely they should have already chased the company for a reply. Surprise, Surprise a week latter I received a letter from ASDA stating that the company and (conveniently?) received but lost the object before they could investigate what it was. ASDA sent me a cheque for a tenner with a letter saying "Go out and treat yourself......." with a tenner? Where was I going to go, The Salvation Army Canteen and blow a whole tenner? I phoned them, they sent me a further tenner but I still wasn't happy that ASDA had not kept photographic evidence of the item before they sent it on to the supplier.
The second time with the grit/quarts I took a photograph of it, made two copies of my letter of complaint and took it to customer services, I was given a refund but when I asked the person to sign my second copy of the letter she refused saying "It's more than my job's worth to sign that letter...." I told her I was writing on my copy that she was refusing to sign and I wanted to see the manager. He appeared and I pointed out to him that he had a self confessed JOBs WORTH working for him. He sensibly stated that the woman should NOT have had any concerns about signing for the letter and item.
I told ASDA that if I had any issues in future I'd consider going direct to the food standards agency.
In the case of the quartz/grit I was sent a cheque for about a tenner with an apologetic letter.
