Very bad service at Hartswater Bradlows

Good day 3_4weeks back I went to Bradlows Hartswater was assisted by the branch manager Anna Kruger to apply for TV license, she told me that unfortunately she cannot help me with it without buying TV .I bought TV and fixed wall bracket. Today I went back to the store to exchange or return the bracket because apparently I bought the wrong one, I was told that they can't help me with neither the exchange nor refund as 7 days exchange policy already passed which I was not told about. I called their customer service as the branch manager didn't want to help and she was very rude, to say I'm very disappointed will be an understatement because the customer service consultant told me I was supposed to have asked for the store policy when I asked him why don't their store consultants inform the clients about the 7 days policy 😕 I'm writing this with a heavy heart and I must say I'm going to spread the word to my family members how bad Bradlows service is.Im also going to write this on your Facebook page.
