RGC walked away frustrated after their 20 - 26 defeat against Pontypool on Saturday.
The Gogs were on the receiving end of numerous refereeing decisions during the South Walians' first ever visit to Parc Eirias, with Kelvin Davies red carded in the second half after a high tackle.
Rugby manager and assistant coach Damian Mcgrath said: “Our initial thoughts from the game were that we were hard done by thanks to some of the officiating - the sending off was very harsh and I think even Pontypool agreed.”
The Gogs competed hard throughout the game despite an opening salvo from Pontypool which left the scores 12 - 0 after 20 minutes.
RGC replied with a penalty try after some strong forwards play with Rhodri Carlton-Jones nailing the conversion.
Another penalty from Carlton Jones brought the Gogs within two points, but Pontypool stretched their lead with two easy penalties in quick succession, leaving the scores 10 - 18 at half time.
The second half got underway in dire fashion for RGC - Pontypool adding another three points to their tally within minutes, with Kelvin Davies sin binned for slowing down play at the breakdown.
Pooler scored again after a huge overlap, but the missed conversion gave RGC a glimmer of hope.
Thabiso Mnongozulu crashed over the Pontypool tryline and Lewis Barker hit the extra points, and added another three via a penalty soon after.
Despite desperate pressure RGC failed to find the try they were fighting for and walked away with a bonus point defeat.
McGrath added: “We had lots of opportunities but we just didn’t finish them off.
“The expectation of these players has grown exponentially since we started and I think once we get that consistency we will be a credible force in Welsh rugby.”
RGC next face Tondu away on Saturday, October 12 at 2.30pm.
Both teams have a record of two wins from five games, but RGC have won both of their away games in the SWALEC Championship and will hope to bounce back from their frustrating defeat against Pontypool.
