Pathetic customer service

Most shocking service I have received from V&A Zara in Cape Town. I bought items on the 17th of January 2020 and went to return it yesterday the 16th of February 2020 (1 month later), and I was told I cant return it because it's more than the calendar month as the 15th of Feb was the last day, which is utter nonsense. When I bought the items I was firstly told that it was for a 14 month old instead the items where for a 14 year old, secondly I was told I could return within a month, ie 17 February, not only did I also question a full calendar month with the manager should be until the 16th of February (17th of Jan to the 16th of February) I was just told no I'm wrong and I should take it up with complaints online. Utterly embarrassing service from a so called international brand. If this is your service and actual level of expertise in a store there is some serious training that needs to happen. I expect someone to contact me to take this further.
