Metrofibre Finance Team Poor Customer Service

It has been more than a month since I changed (ISP) provider. I have a credit on the account with Metrofibre and have made several follow up calls and emailed their Finance team to advise regrading the credit due to me. I provided the required documents needed and have since been waiting for the refund to occur. Each week I am told that the payments occur on a Friday and they will follow up on when their management will release the credit payment. Poor customer service from their Finance team. No one takes ownership or accountablity.
