Poor / Unprofessional Service

PEP Stores (Cell) Westgate Branch: On Sunday 20/08/2018 I had gone to the mentioned branch returning a mobile phone I had purchased less than a month ago from their Mobile Cell section due to a faulty charging block / Pin. Firstly, they had no stock available to replace the unit and only had a more expensive model for which they wanted an extra amount to be paid, we requested a refund on the unit bought and the staff refused to even conform with that simple request. Secondly, there was no senior staff on duty not even to mention a branch manager or even a person appointed as acting manager should there not be a branch manager available. A cashier by the name of "Thandiwe" seemed either to not understand or so poorly trained regarding the return / refund policy and her unwillingness to assist that it caused great visible frustration for myself. She (Thandiwe) pushed the mobile phone and documents back over the counter towards me not asking but instructing to come back when they have stock or when a manager is available. I work shifts and thus makes it difficult to just go and have the matter resolved. Very poor service to say the least. This cashier should be DISMISSED not even reprimanded.
