Processes that affect the customers / No follow up, no communication / Courier It lost device

Upgraded with Cellc the device got ****** before it reached me( I say this because the courier driver never got to my place or even called me to inform me that he/she is delivering my device however on the Courier It app it said I was unreachable) after days of calling the courier It company and CellC only then I discovered that the device is actually nowhere to be found, why is it that I need to be the one calling as a customer of Cellc to follow up ?? I have not business with the Courier company Cellc needed to ensure that I receive the device now I can not cancel or do anything I need to wait on Cellc and courier it to sent each other information and documents in the interim I the customer of Cellc is being affected. This is just so frustrating I've been with Cellc for years and I really do not expect such , changing from Ram to this nonsense courier It was a bad move their reviews are horrible to read...... I am tired of being taken from pillar to post for such , clean up your house and ensure that the processes implemented do not affect the customers because this is really frustrating and annoying I upgraded at that time for a reason now I need to wait for your processes that affect me to happen its just not fair. I can not stay with such Ive been loyal for years but this right here is a deal breaker.
