I had an issue with a tablet I purchased. This was sent away for repair. To be brief there was a long drawn out issue re the repair_the store staff were rude which prompted me to ring head office. After much debate it was found that the repairs had confused my product with someone else's and my item would be returned within days. The manager I spoke to apologised and as a good will gesture refunded my postage costs and said I would receive a £25 voucher. That was at the begining of Oct. This has not arrived. I rang the office and was told I needed a reference number which i should have had from the manager if not they could not send voucher. I am furious, if this is meant to be good customer service it is sadly lacking. There was no record of this conversation I had had and no notes on my account and staff that do not know the system.. I will never deal with Argos again after this fiasco.
