Cell C poor customer service

I am very unhappy and upset with the work ethic of Cell C staff at the Workshop in CBD, since the 17/08/2020 to today I have been awaiting them to send through my information to the cellphone insurance company , I have followed up with them twice through email with no reply and their landline phone rings with no answer at all, the staff have no care at all for customers because as well as on the day I had gone to fill in the claims form, it took me close to an hour to complete that process because no one cared to assist me but a friend of theirs walked and got immediate assistance and as far as my memory serves me there was not manager on site. I am very upset and disappointed with Cell C
