Sadly The matchmaker will not come for your tamagotchi oldie, the matchmaker does not come for olides. However you can mate with another oldie and get a surpise..
Yes, you are out of luck when it comes to the matchmaker, unfortunately. D: However, if you have a friend who has tamagotchi connection or if you have a second tam, you could always just pause your current oldie and raise the other until it turns into an oldie, and then breed them. As locky noted, you'll get a suprise.
