Not Customer Service Orientated At All

Totally disgusted at the service from Sportscene. This is the second bad experience with this retailer. They are not customer orientated. I called Sportscene Promenade branch on Monday 20 January 2020 a young girl answered the call and i asked if i could speak to the manager and she advised that the manager was on a call but she would get him to call me back, however she did not ask all the relevant information to relay to the manager, for Example, my name. The manager eventually called me back about 10 minutes later and asked "Uhm Hi, did u call a few minutes ago not addressing me on my name as he did not know my name" how unprofessional. i explained the problem to the manager, some time in December or beginning January i bought an ADIDAS dress R550, however i did not fir on the dress and when i wanted to wear the dress last week Saturday i noticed the dress was to tight and because i am a muslim lady, i do not wear my clothing tight and all clothing needs to be long length, i went to Sportscene to see if there was anything else in store i could change the dress but did not find anything else which would fit my dress code as a muslim lady. I then planned on taking the dress back and realized i cannot find the slip and that is when i decided to inquire what i stand to do as i dont have the slip and cannot find anything else that i like and tried to find out if there was anyway they could take the dress back and give me a cash refund as i bought the dress cash but this obviously would have to be with a slip, unfortunately i could not even remember the date when i had bought the dress if it was december or January as i made a few purchases in December and January at various different sportscene stores, i only remembered that i bought it at Sportscene Canal Walk. The manager advised that he would contact the branch where i bought the dress and ask them to try and trace the slip and since Tuesday 21st i have not had any feedback related to the query, He messaged me on the Tuesday saying they are still trying to trace the slip, however thereafter no further communication so i am in the dark with the query on what it is they can do to assist me or i will be a loser of R550.00 for a dress i will never ever wear.
