Bad billing systems and customer services

Their billing systems are quite deceptive. I was taken aback to discover my Wi-Fi was disconnected on the 1st of the month, even though I had made my payment on the 30th. It’s even more frustrating when they start sending out bills as far as from two years ago. It's unrealistic to expect someone to remember something that wasn't brought up at the time. Additionally, customer service is not helpful in resolving these issues. I cannot recommend this service provider.
