MTN & Idroid Lab Failed Device Repair!

Have been paying R93.86 every month for device insurance only to be failed by it when needed. Paid the R150 co-payment, device was collected and two weeks later no news or updates. Decided to contact the courier company listed on the courier receipt (IdroidLab) and told them to return the device to me. Device was returned and it was still broken. MTN is now refusing to provide me with a replacement device and my queries are simply falling into the dark void that is cellphone giants these days. Utterly disgusting! You have had the opportunity to repair the device and have failed to do so. Issue me with a new device now please! I refuse to be inconvenienced again by having the device repaired and sitting without a device for 2 weeks!
