Insurance not offered

Around 2 weeks ago i upgraded my package online and ordered the Huawei P30, I have done research on the phone and noticed the value of the phone was quite high, therefore it would be best for me to insure my phone. i have contacted Telkom today and requested to ensure this phone as i saw this option was available online. I spoke to an agent by the name of Rosswell who told me that i cannot insure the phone as i have exceeded a window period of 7days. i was given the contact details for a 3rd party (Finrite) to contact for this cover, and now i need to head to a telkom store to insure, but the Head Office already informed me that i exceeded the window period.

Telkom is a service provider, and part of this service is sales. This service was not offered to me at all throughout my upgrade process, and i am not comfortable to pay R500 a month for a contract in the event of losing the item. I need this cellphone insured urgently!
