pathetic service and attitude from Manageress in AmericanSwiss Bayside Mall

i have received a gift from my sister for my birthday that was on the 9th of February 2017, a gold bangle with the value of more than R3000. my sister has bought the gift days prior to my birthday and also asked them to rap the gift. eventually when she gave me the gift on my Birthday the 30 days from when she purchased the gift has already passed. due to the fact that we do not live together i asked her to send me the receipt of which she did, i then went to the store in Bayside Mall and was assisted by the manager whom was a female. she told me in a very aggressive manner that the person that bought the bangle needs to come in her self. another month after that 14 March 2017 Alecia has taken in the bangle and they said that they cannot repair the bangle. i then told her to leave the bangle there as i will go with her. we went together after that and the same manager with her attitude was very rude and said that she assisted Alecia when purchasing the Bangle (Susan) and she did not see any damages before she rapped it, i told her that it is ether they will fix the bangle with the dent in or refund it back to Alecia's account because i will not pay for something for that amount of fund and not even be able to wear it . she did not even go the extra mile to try and assist as i am the client, she only walked away with her attitude . till today the bangle is still at Americanswiss bayside mall and they do not even call to apologist yet alecia is not even owing on the bangle . i want her personally to apologize to myself and my sister for having such a bad attitude, i want a the bangle to be fixed or the amount to be returned into her account and i will never ever buy anything else at AmericanSwiss bayside as it feels like the manager has ****** issues .
