Second month with annoying service

Im really not happy with your service , please can someone have a look into my billing from January to the current month . I need you to investigate how much i should be charged each month and how much i was sharged and why. The chat consultants refused for me to speak to the team leader as she says i need to call the call center . i find that very rude and condesending especially considering how much i spend each month. i need for my bill to be sorted and i need to knwo why i was billed this much . After i went to the walk in center my bill was not correct so we need to start there please . I paid up to date last month but my bill is high again.
