******** billing system

First and foremost the sole star im giving you guys is simply because i had to choose a rating but honestly you deserve nothing of a star. Ive been having issues with the billing system, my bill is never the same on a month to month basis, number 2 my services were blocked on the 16th whereas my due payment date is on the 17th of every month. i always call only to be told that my issue will be escalated to the billing department and they will call in 24 hours, ive been hearing this story for the past 4 months and no one from the billing department has ever called. now my bill sky high again this month and consultants cannot give a reason and when you request to speak to a supervisor they are always in a meeting or they are on leave. last call i made was on the 16/08/2019 and spoke to a Hazel who sold me the story of billing department, till today nothing.
