Unable to Reach Kraft Customer Service for Techno Signal Car Seat Cushion Replacement

I am trying to purchase a replacement cushion for my Kraft ST-2 Techno Signal car seat. However, no one answers when I call Kraft customer service at 02126969541, and I haven’t been able to connect with technical support despite repeated attempts. The phone rings, but no one picks up, which is extremely frustrating as I only need assistance with this simple request. I’m disappointed by the lack of support and responsiveness from Kraft. Does it really require filing a formal complaint to get help? I would appreciate prompt assistance in securing the replacement part for my car seat.
