Still no Feedback

I'm extremely disappointed in the type of service I received from MTN Insurance, my phone was collected 2 weeks back, every time I send a email to MTN [Email Removed] they just read and no feedback I have some client information on that phone but i have to wait i don't know for how long now to get my phone back, what's the best about it no one even contact to say why i even send emails to Celiwe Nkosi she only just read but don't reply. All i want is feedback and when i phone i have to hold on forever and no answer. CAN I PLEASE GET FEEDBACK?
