How do I pay...

Hi guys... Listen... Not sure who does the quality control on any of your systems but your invoice you are sending me on email does not include your banking details or what my ref must be... All it has it a slip to be cut off to pay manually... Then why bother emailing me the invoice... If I wanted to print it I would have asked for a mail copy... 2ndly, your online portal detects my account but doesn't detect any outstanding invoices although your same system is telling me I'm overdue. I can't progress here to pay my account either... Come on... I even noticed on my invoice you have a completely wrong address... How did the installation guy manage to find his way to me when you installed it in Sandton when the address you have for me is Kempton Park...
