Bad service at Identity North Gate mall

Have never ever in my life ever received such pethetic service... I received a call from identity store thanking me for my payment and recent purchase at their store, as I proceeded to listen the guy that called me said they wanted to offer me an increase on my credit limit, while I was still listening the line cut.. I then decided to drive to my nearest Identity store which was North Gate mall... I got there and related my story and asked them to check for me on the system, which they did and found that nothing was updated I then asked they call which ever department that is responsible for making these calls and find out what happened already the lady called by Dephney was running out of her patients, after calling the the department she comes back to me with a very stinking attitude telling me that my account is only a month old with them how possible is it that I can qualify for an increase, she basically refered to me as a lier and told me whoever that called me was just doing a routine check of my experience at the store that I bought clothes from... We exchanged words to a point that I asked for her name and surname, she gave me her name and said I must see to finish how I get her surname...

2ndly I wanted to exchange t. Shirts that my daughter received as a gift since they were too small, now I had to deal again with her telling me that if I don't have the card that was used for purchasing the gift then she cant do anything for me, that's again where I flipped, how do I get a card that was used to buy my daughter a gift???? Since I insisted she needed to find ways of helping me she took her own time in calling in for authorisation which ended up with me been given a gift card... Why wasn't this option given to me from onset when we couldn't find the bigger size we were looking for cos I stated from the beginning that it was a gift????Had to stand 30mins for your staff to assist me in a very stinking attitude.. I will personally no longer shop at identity if this is the kind of service you train your staff to give to us and will never recommend it to anyone especially Identity in North Gate Mall and will use all social media platforms to make sure that this never happens to anyone else!!!!
