Cell c to take responsible by investigation as to what was the reason for the blast and explain in future to the customers

They failed to apologize and answer questions that were supposed be answered by them regarding the blasted power bank and instead they wanted to just replace it by not giving me safety and how to deal with my colleague who inhaled the smoke during the blast or exploding power bank. That smoke affected her real cause she is went to doctor. I don't know what to do about this. The person who was made to apologize, wasn't even the person who sent to East gate and East Rand mall.
