MTN still not responded to my Hello Peter complaint dd 27th July 2018 - a week ago?????

I logged a hello peter complaint last week Thursday 26 July 2018. They responded the following day. MTN apologized for the inconvenience caused & acknowledged that their call centre agent gave me incorrect information about the Samsung Warrantee i.e. my phone was covered for screen damage BUT "sorry cant help you" go to Samsung with your complaint. I informed them that I was an MTN customer, not Samsung & that it wasn't my problem that agent gave me incorrect information about the new phone I had just purchased in March 2018. MTN should pay for my screen replacement which is R2500??
