Angry customer Ingersoll Rand

The service received from Ingersoll Rand staff has been shocking. Elizabeth Makoena is extremely rude and unprofessional as well tellephonicaly and via email. The mark up on spares bought is ridiculously high and waiting period is very very long. Getting money paid back that was initially paid to Ingersoll Rand but spares not received on time had me getting the same spares from another supplier for much cheaper as well as very swiftly. It's been weeks trying to get them to pay back the funds that was made to them. Getting a response from Edgar and Denise is another story just empty promises of payments being made but no action and simply no response on any requests whatsoever.
