No Support, No Customer service

Debit order dates, line speed and line latency issues, can't run voip. Biggest issue is billing times, used to have debit order on the 15th of each month, always eft on round about the 7th of each month, no issues. Then my payment date changed and I moved it to the 1st of each month, endless problems, try to change it back, then it's just sorry, it has to be the 1st or 25th. Ok, told them to keep it on the 1st. Yesterday, internet went down, no support on sundays, so phoned this morning to find out services is suspended dew to non payment on the 25th, I asked them u put it through on the 25th? No body knows, for people that works with computers this is not the correct answer, go check the log. Now I still struggle to get hold of anyone at home-connect, no replies, no help, nothing, absolutely useless.
