Bad service at Keedo Mall of Africa

I had an item I had received as a gift for my son which dud not fit him. Ithen took the outfit to Keedo Mall of Africa to exchange for the right size, however this was not handled well at Mall of Africa Keedo, the lady that receive me asked for my numbers and said she will ask the managers call me to no avail. A week later I realised that I was not going to receive the call as promised, as a result I left as an unhappy customer and as a result I've resolved never to buy at the mall of Africa Keedo outlet due to their bad customer services, over promising and not delivering, very disappointing.
