Worst service received from Mike's shades

Worst service ever! Received a quote for a shade port: been battling from that point to discuss colour of steel and shade netting. Calling Mike is impossible, calls are never taken. Options for colours cannot be discussed, you just take what you get. The product that was delivered is not what was quoted on, no feedback on who changed the order and why, just expected to pay 30% extra... Invoice details are not the same as on the quote. Not sure why the invoice does not reflect the same details. I just hope that no after-sales service is required, if this is the pre-sales service that I'm getting...
