Very unhappy client

I sent the below email and not one rep****, I not sure what to do to get serviced? Good day

Please assist, I don’t understand why I have to write emails before I get serviced.

Margo promised to call after she has corrected my account and she did not call AGAIN!

I am very unhappy with the service I have received thus far.

Can I please ask for someone in management to call me.

I don’t understand why my Bill on my Vodacom app say I have to pay R2194 which is a difference of about R106 from what I was paying before as my bill was R2300.

I settled 1contract which I was paying R403 for and I settled a handset instalment on the 071 number which I was paying R112 for. This is a total reduction of about R500. So my bill is supposed to be R1800 or less.

Please fix this account and please get someone in management to call me because I am not happy at all.
