I would like to put an official complaint regarding the service i experienced today at Trade route Mall Ackerman's today . I went to exchange a buccaneer shoe which i had laybyed and due to the lockdown i couldnt exchange when the size was wrong Today i went to exchange the shoe and they told me to pay extra amount because the price had increased when i questioned that i recieved rudeness and bad attitude from the staff who then referred me to Sandra who is the manager she was just quick to tell me i must call customer service if i have a problem,

Now i am not even complaining about the extra price i had to pay due to the mark up i am just unhappy about the poor service i recieved from Ackermans trade route mall from Khululiwe and Sandra.very Rude and do not have customer care i still dont understand why am i supposed to pay extra for something im exchanging .
