Poor WiFi provider

This company require you to pay your account BEFORE the first of every month, in advance. This is before any service is delivered. I paid them on the first of the month in full and they disconnected me. They now say I must first pay a FINE before they re-connect my WiFi. This is because I bank with a different bank than them. After numerous email communication from me requesting the contract I signed stipulating these rediculous terms, they don't reply and just cut my WiFi that I have paid in advance in full. I most definitely will not recommend this WiFi service provider.
