Bad service and inconsiderate of clients

They do not have a sense of emergency and do not take note of clients frustrations, I had been handed over for cellc account to them and they have never been consistent when it comes to our agreement to debit R300 from my account, now whenever I request a full statement like I did now show all transactions they do not respond to any of my emails, they never even changed the amount I was handed over with even when I was paying. Been communicating with cellc and they have been calling to provide feedback but there's no way forward for us because SSDA is not providing us with the information we need.
