I am being overcharged and now I'm suspended

I am very upset my account was fully up to date do I ordered a rain loop 2 days ago I made it a collection I paid on line the pro rated amount it went off my account and my order was confirmed and now I wake up on a public holiday to find all my services are suspended my rain 101 pro and my loop because of a outstanding balance that I was randomly charged and its the same pro rated amount i already paid this is unacceptable of rain to suspend me like that a paying customer and overcharge me I am beyond disappointed now I'm sitting without internet
