Bad Service from Khayelitsha Shoprite CBD

On the 11 called the Shoprite Customer care number, spoke with Lukhanyo and address the fact that when I was a Shoprite Khayelitsha CBD was attended by the Lady who is the Manager of Second in charge in exchanging the size of the nappies I bought on the 24 November 2018.

The size I was returning was size 3 wanted a size 4, instead of a exchange the store returned back the size 3 and with the refund, had to pay the difference to get the size 4. Ask why they not exchanging the size as size 4 was also running on promotion on the 24 November 2018, when the purchase was done.

The Lady responded "the store do not recall the items which where running on promotion on the 24 November 2018, that is why I must pay the difference"

Called the call cent re while I was still at the store and Spoke with Lukhanyo, I was promised that the store will get back to me the same day to resolve the matter.

Call several occasion for feedback still was promised that the manager of the store will resolve the matter.

Today is the 24 December 2018 and I spoke with Megan still the matter is not resolved yet.

Unsure whether it is the fact that I am Black South African, from Khayelitsha?

But I do not see urgency. Treated like trash from where I throw up.

I would like to know if I customer is unhappy about certain service what is the correct manner to follow to get the matter resolved ASAP.
