Changing payment cycle date

I am here to inform anyone that is considering having Fly.Cool as a service provider, for internet connection that they provide he worst customer service I have ever come across. Their clients are the least of their worries, as long as they receive their due cash. I have been allocated different consultants to assist me in changing my monthly pay date to the 1st of every month as opposed to the 18th, which is mid month and very uncomfortable on my month to month budget. However at most, a consultant will reply on email, but no actions or follow up will take place. This is now my 3 month with numerous attempts, but I have still not been assisted. Instead i have been fed empty promises on email.
