Mtn Hemmingways incompetence

Wow! I don't think I've ever had to deal with such I competency in my life. MTN Hemmingways in East London is where I took my phone in for repairs on 4/09/2020 and it was within warranty. The consultant who assisted us advised to only deactivate find my iPhone a nothing else(mind you he was preaccupied with his phone during this whole time). I do not know mtn policies so he should have ensured that told us to remove all security measures set on the device. I even asked him if that's all we needed to do and he said yes. 4 months later, I'm getting a call from the store advising that they will not be repairing the decide under warranty. I will be liable for a 4k charge because the phone had a Pw when it was taken in and is now out of warranty. If you're thinking of taking a contract with them please think twice because wow! I am honestly appalled at their customer service. I am definitely canceling my contract with them, I paid my installment every month for a device that was in their possessions only to be told it won't be fixed. Truly interesting
