Unrelaible service

Good day I'm experience a problem for some time. They've stopped my service with them without any warning and for no reason.I experience this problem from the end of May 2019. The reason the claim is because that did'nt pay account,that not the problem.They told me that I must first pay a certain amount,which usually is dubble of what my account payment is.One time I've paid three times the amount.Thye then said that my sevice will be reconnected between 2 and 24 hours That don't happen I do have all the paperwork that shows that I'm not at all behind with my payment. I use this number to do my business with. This situation is totally unecceptable.
