Bad Customer Service

Good day, I was at the store on the 25.06.19. Purchased 3 items for my daughter.On the 29th of June I phoned the store and spoke to Katlego (Flexi staff member) as I wanted a bigger size in the track pants which their system showed they have. But unfortunately KG couldn't assist because he does not know how the pants look like and they have a lot of stock for him to actually know that. I was then passed on to Hilda who introduced herself as the manager and tried to help me find the pants from other stores to realise only their store had it and was to pass on my complaint to the manager coming the next day. On the 2nd of July I phoned the store again since nothing had happened since then and spoke to Simon who is also the manager there but said he knew nothing about my complaint and Hilda had been working in Menlyn that day,told him the story again and he was to get back to me. To this day I am still waiting for his call.
