Poor customer service

We bought chicken from the sheerwood Spar and when we got home we realised it was off and we took it back. On arrival we went to the kiosk and requested for the manager. The cashier took the chicken and went to go speak to the manager. We were then told the manager will issue us the slip and when the slip was ready the cashier just came back and asked us if we would like to take something else or cash refund. We were shocked because we had asked for the manager and he never came to us. We had to insist in order to see the supervisor by the name of Melanie which she showed no interest in what we had to say then the manager by the name of 'Eric' told us he was not aware of this issue meanwhile they had been sending the cashier to give us our refund. The customer service was so poor especially from the people who should be superior. We eventually asked for the people above them and the info was not forthcoming which ended up in a frustrating situation from our side. This whole situation could have been avoided if the manager had came and spoken to us as he should have instead of not wanting to speak to a customer!
