How Musica treats loyal customers

On 10 Dec I purchased a ps4 bundle at Musica Canal Walk and was assisted by Simone, at no point during the whole sale was I informed that I would not be able to return the console after it had been opened. I purchased the console as a gift for christmas, and that being more than 14 days away i had to open and test the console before wrapping it up, I then saw a discount on the exact bundle two days later and was refused to return the console due to it being opened by the store manager (Chantal) and her assistant manager (Natalie). The console wasn't even sealed on the correct side to begin with and therefore I was also sceptical about it being a working console. At various other Clicks partners when purchasing expensive items they would inform that they have a sale starting in a few days and advise consumers to rather wait a day or two and then come see whether that item has been marked down. Instead Musica decided to have a loyal customer purchase at the more expensive price rather than advise to wait the two days and come back to the store.
