Poor customer care, poor management s****s

On 29/11/2019 I bought lot of new born clothes thinking they have black Friday, then on monday I had a surprise baby shower then realised I have a lot of new born clothes and went to exchange sizes on the 4/12/2019. I got to Pep mark park Vereeniging and asked the lady who is working there and was walking pass by me where must I go to exchange she pointed with her hand backwards I couldn't understand and went to the security officer at the door he said I must go to the till, there was a queue and i joined got to the till the lady asked why did I enter with clothes that i want to exchange in the shop i told her i asked and I was told to go to the till, she left me there not saying anything and came back with the manager he asked me the same question and he said who is the lady I spoke to I rep**** I don't know her but 1 of the ladies here and the security officer, the manager said the till lady should call another customer i was surprised that they wont help me because I dont know the lady I asked and i refused to move away from the till then the manager said the till lady should go do something else he mentioned this retail word i think it means pack the clothes so they left me there. I was with my mother she went asked why are they not helping then I asked the security officer next to the manager whether I did ask him where to go or not he popped his eyes out and mumbled, the manager went back to his office I asked him to give me my receipt my mom gave it to me I didn't realise she had it with her and we left without the clothes being exchanged.
