we reported a malfunction problem which then settled on its own. We were offered a paid intervention for a technical release. very "listless" staff who asked us to pay in cash and did not issue us any receipt. two days later we receive the unilateral cancellation of the contract due to "technical problems". Indecent behavior to terminate a contract perhaps not + economically advantageous. unspeakable behavior.
