Poor customer service

Terrible customer service. Very impolite. They did not send me an invoice as they said they would. Then arrived and although I was busy with loading the payment the technician stood by waiting instead of performing the service for which he had come. He did not bring a printed copy of an invoice with him but gave me his personal tablet and expected me to work of that for the payment. Then he asked me to print the POP for him. At that point I was so annoyed by this behaviour I asked him to leave. This is not a good way of treating people and I won't give my support to a company that behaves in this way to customers.
