poor service

For the last 8 months I have been trying to get my tax invoices mailed to me at the end of the month. Every time I just receive a statement. I have been phoned customer care every month and still no one solves my problem. The phone is being used for work and I have to claim the money back. Now For 8 months I could not cause I don't receive my invoice. Also I am being charged for itemized billing which I also do not receive. Their service is really poor.
