Bad Service

We went to Telkom store as we have some billing issues, while being helped the lady just got up and started helping other Customers. We have some issues as to amounts of R1000 and R1200 being debited phoned the call centre and as per them, my account due is R618, and nobody can tell me where these amounts that has been debited come from, my phone has been suspended and I received a message yesterday stating \ make payment of R1000.00 on your Telkom Mobi into ABSA at NuDebt". This is really poor service from telkom"""
