pour service and their staff members are so arrogant.

I'm not happy with the Blue label customer service that they gave last week Tuesday 19th October 2021. I bought the phone in July this year and then the battery decided to no longer work.I have lodged a complaint but no one is willing to assist. they told me they will call back within 72 hours but till today, we are in a new week no one bordered to call me back.
