Lack of feedback

Hi<br> <br> I've recently taken out a contract with MTN and required insurance on my new device.<br> I emailed the relevant division and received forms for my completion on 31/03/2016. This was returned to MTN on 04/04/2016.<br> I gave it a couple of days and then followed up on 06/04/2016 ; again on 11/04/2016 and then again today 18/04/2016.<br> <br> I would appreciate if someone could get back to me and confirm that my documents have been received in good order or if no response is going to be provided I will get my device insured elsewhere.
