Honor 90

I've upgraded my current contract with MTN Cradock in the Eastern Cape, received the phone on 29Nov 2024,never used the phone till the next Monday to take it back to the store to transfer my information to the new phone, afterwards I realised during the first week that I have to charge the phone twice a day, I report the matter to MTN Cradock, they advised me to bring it in to the store for them to monitor the battery life, that was on 07Dec, I got it back same day and it was fully fully charged, same thing happened, when I called them back on 11 Dec reporting the same matter the store sales consultants were very arrogant with me, saying that I am the one who is having a problem with the phone, so now I don't know what to do since I will be paying for the next 3years and sitting with a phone which battery life does not last a full day. I am totally not happy with the service that I've got from the MTN Cradock store
