Poor Services from consultant Jabu

I contacted mtn call center on the 12/02/2021 i needed help my account was handed over to there legal department. I requeste the paid up letter as the payment was done after finding that im on legal department using this number 083 135 they manage to assist me and they send escalation to there legal and i was given the reference number *** they say turn around time is 3 to 5 working days but i haven't receive anything. on the 26/02/2021 i make a phone call for a follow up I spoken to Jabu who gave me poor services from the beginning she answer the call and she was very very very rude to me she said she can't help me as she don't know the legal department I must find out on my own she can't assist me. Then we heard an argument she mention that I'm not a good listener she can't deal with me. In that moment I'm in need of this letter I have to start new job but because of this can't be helped due to poor services that I received from mtn employee.
