On 28th April 2018 I decided to purchase a new Samsung 55MU6220 55 inch curved 4k UHD smart tv with HDR. To say this was the start of a process that can only be described as a nightmare is an under statement. When completing the purchase under the `special offers and frequently bought together` there was an offer if you bought the sound bar listed, namely a Samsung HW-K335 120 W 2,1 ch sound bar with sub woofer. you could claim (after 30 days from purchase) £200 cash back from Samsung. I hadn't thought about purchasing a sound bar, but the offer seemed really good so I decided to purchase the specified model. The first issue I had was the sound bar would not connect wirelessly to the TV. I contacted Samsung Support for advice and was told this was because the model of TV I had purchased didn't have blue tooth. I contacted Argos as the TV purchased clearly stated on your web site that the TV did have Bluetooth. I was advised the description would be amended. I explained that I now would need a cable to connect the sound bar and requested one be delivered to me free of charge. A cable was delivered but it was the wrong one, so I had to go and purchase the correct one from my local store. At the end of May, 30 days after I purchased the TV and sound bar, I submitted a cashback claim to Samsung. Between this date and 23rd June I submitted the documents they requested as evidence on 4 separate occasions - on the first 3 occasions they said they were blurry! I finally received a response to say that `the model sound bar purchased is not a qualifying product....and I won`t receive the £200 cashback. This whole process has left me extremely angry, I purchased the TV and Sound bar in good faith, as described by Argos, and as part of a cashback promotion advertised by Argos. Argos is guilty of mis description in terms of the TV and cashback promotion. They are now asking me to provide evidence of the promotion - unbelievable!1 Don't buy from them !
