Great service but... no so useful

<p>I have some issues with Cobra parts failing on a yearly basis. Cobra sent their guys out, had a look, advised me to balance the geysers / house.</p> <p>So at least they came out, but can't be of more help. Will balance the house this week.</p> <p>Next time offer to balance the stuff for me, bill me 2 hours of work and Cobra parts, would have been happy to pay.</p>
