Refund on account

We have terminated our service with metrofibre and there is a credit of R460.00. I contacted your Account dept and was told to send confirmation of my banking details and will be refunded within 30 days which is also ridicilious. I contacted your account dept today just to find out that the agent that I spoke to on the 7th August didn't even load the refund. This means I have to wait almost two months for a refund of R460.00. I expect mertro fibre to refund me immediately. The account holder is C de Villiers
