Bad service from consultant and then explaining the matter over and over

So I recieved phone calls regarding the bad service i got from vangate mall cell on the 30Th April 2019 firstly it was a women who stated shes escalating the matter to head office which i agreed no one should be pushed around by bad service . Then later after that the manager of cell c vangare mall phones me telling me to explain to her what happened as she recieved an email i then had to explain my self again then i told her how good the service is at promenade mall cell c is and how bad the service is that i got at vangate mall the consultant asking me to get a bank statement not specifying current or your previous bank i then had to sit and wait for that statement in the bank wasting my time only to go back to the vangate mall consultant telling me she cant use my bank statement she then makes me believe she tried sending the statement to cell c cause she took it then said i should pay by netbank making me believe she did something with my bank statement she then told me it takes 7 days if i pay by Woolworths to reflect next day got to cell c promenade the other consultant from promenade stated it takes 24 hours to reflect i could see she really wanted to assist me not like the vangate cell c consultant the vangate mall cell c manager then ask me to identify who the idividual was that gave me bad client service by sending pictures of the staff at vangate mall i then identified the women after that she sent me a picture of cell c staff in promenade too I identified the women who gave me good service . The lady who gave me good service the sale consultant phoned me today telling me well asking me if I could send an email to cell c with regards to she gave good service i then told her she assisted me but my question is why am i having to explain my self to all these people im not sure if she was under the impression that she gave bad service because she said she saw an email im not sure what the manager of vangate mall stated in that email all im saying is she needs to sort her staff out in vangate mall and not having consultants phoning me from promenade to ask me to send cell c an email to tell them i was assisted she should focus on vangate mall cell c please cell c correct your service by getting people to do their work correctly also I want to say the women at promenade that asked me to send an email she seemed confused no one should feel that way and i also shouldnt be questioned by 3 people having to explain my self what is this cell c should fix there service clients shouldnt need to be phoned and then having to explain them selves over and over !!!
