*** is wrong with your people?

*** is wrong with your call centre??! I have not received my e-Invoice as yet. i phone customer care, they cant help and put me through to some another call centre. I speak to that lady, she says i must speak to customer care, takes my number and then immediately transfers me to the same customer care that cant assist! Pathetic service! Should i rather stop my debit order, since i have no way of knowing how much you will be billing me?
