Bad service that i received from Identity

I once went to a store at Identity and looked for a top that they did not have a size of. They then called the nearest shop to check if i can get the size. Then they confirmed that they do have the size. I gave my name and contact so they put the item aside for me to collect later that day. Unfortunately i couldn't make it i went on the next day and i was told the item is back to the floor as they keep for a day only.

To my surprise i went to the tops to look for my size and i found that is only one left and that item still has my details on it. I took it and fit, after i went to the cashier to pay. When i got there i asked the person who was helping me to pay that how come i find my details on the top on floor where everyone sees them. The lady said is not me, she never said i apologies its a mistake no. I took a picture of the top. Then i asked for the manager why this? Her respond was "even if i ask no one will say its me". she did not apologies or anything like that.

I left the store with a broken heart, as i love what they sell but the treatment is not what i expect as their account holder customer. After that i called their client service to launch a complain. They gave me a ref no. Then i was called by the manager to apologies. I said to them that i cant take your apology this easy because i left your store without anyone of you saying its a mistake we apologies. Now i used my own money and phone to hold line to be assisted by client service to launch the complain then you are forced to apologies.

She then asked what do i want, i said i would like you to give me a voucher to compensate me. I did not say the price but she only said i will ask the area manager with this regard. She later called and said i asked but till now i am still waiting for respond from the area manager. Weeks are passing by and nothing from them.
