Waiting 3 Months for Medtronic 740G Insulin Pump Replacement

I was informed that my malfunctioning 740G insulin pump would be replaced under warranty, but it’s been nearly 3 months, and I’m still waiting for the new pump to arrive. Reaching Medtronic’s customer support has become almost impossible, and I have no idea how to resolve this situation. I urgently need assistance in getting my replacement pump or at least a clear update on the status. This delay is unacceptable for such a critical medical device, and I expect Medtronic to address this issue immediately.
