The player is still owed the remainder of his enticement fee due him for signing for the club in 2013.
The former Medeama player broke his leg at Kotoko's Adako Jachie training base last year and underwent a successful surgery.
He returned to training on the pitch in January this year after his long dormancy but his contract run out on June 1 but according to the player, the club are still indebted to the player.
“Of course there are some monies they owe me. They invited me on the 17th May 2016 to talk about my future," Koomson said in an interview Metro FM.
"They told me the coach (Michael Osei) said he does not need my services in his team. I agreed. I told them I had no problems with that but they should give me the remainder of my enticement fee and my necessary particulars. They promised to give me the amount after their home game on 25th May (vs Inter Allies) that they will get money from the gate proceeds of the game to pay me off.
"After the game I went to the Kotoko office to take my money but they told me a different story. They again promised to give me the money after their next home game against Techiman City on 29th May and again they did not give me the money. I have to take the money. Its my entitlement but they keep on telling me stories.
“Kotoko is a big club. I am a footballer. I could return to the club you never know. There is always that possibility in football and that is why I do not want to have problems with anyone at the club currently. They should give me my money and I leave peacefully. I have been very patient with the issue because of my love for the club but looking at what I passed though and how they keep on telling me different stories, it doesn’t help at all,” the talented attacking midfielder added.
Koomson signed a two and half year deal to join the Porcupine Warriors in December 2013 and went on to help the club win the 2013/14 Ghana premier league.
