Bad Store Manager attitude and service

Bad experience at Westgate Combo (downstairs) Rage in the Westrand (Roodepoort).

They didn't have a shoe size for the exchange and then the Manager Maria was unbelieveably rude, unhelpful, disrespectful to me as a customer requesting to be assisted and the other shoppers in the store. It took for a shop assistant to assist me after i called the Rage customer care number and they promised to call back and also failed on their part. Up until this day, i was a devoted regularly Rage customer and i would always buy in bulk but clearly we are not valued at all. I suggest managers to be sent for training on how to handle unsatisfied customers in a manner that protects the the brand. She behaved like she was at her mothers shop in full view of all other staff members.
