Kiwi.com complaint: Round trip Madrid-Armenia-Madrid

On July 9 I made the purchase of flights Madrid-Yerevan (Armenia) with stopovers in Vienna and return in Rome for a price of 268 euros, to fly on October 4 and return on the 10th of that same month and this year.
On July 22 I receive notification that the last flight of the trip (Rome-Madrid) has been cancelled. For this reason, I request a full refund of the flights.
The airlines involved are Ryanair (Madrid Vienna) and Wiz Airlines (Vienna-Yerevan and return Yerevan-Rome-Madrid)
On August 17, I was informed that the reimbursement of the last flight (Rome Madrid) has been authorized, returning 25 euros, leaving 243 euros pending.
In different messages they give me contrary information, some that there is nothing more to return and others that this is only a partial return, leaving the rest pending
Today, September 2, I am interested in the situation and they tell me that there are no pending returns, that they apologize for the inconvenience caused.
