Service Provider not Providing a service

Having an issue with MTN insurance. Firstly their call centre is not efficient and does not work. Whenever you try calling in the line gets cut even from a branch. I then went and tried to claim using the online form which is available on the MTN Website, 8 months later and I am still waiting. I eventually went into the repair centre where they took in my handset for the necessary repairs and a day later got an email to state that I can receive a replacement as my handset was too badly damaged. <br> <br> When I got to the store they told me that I was under insured and needed to take a cheaper phone, this was where everything went wrong. Emailed the insurance people again to express my dissatisfaction on to then end up speaking to a lady by the name of Zaida Khun who rudely said to me that if was not happy with the resolution I can cancel my insurance and move to a different insurance company and that she would do me a favour and cancel it immediately.<br> <br> This is pathetic service from a so called service provider
