Bad service from RAIN Internet Service Provider

Not to be funny or anything but this is a company that makes South Africa's name bad. The customer service division is not existing. When you send them an email, they don't reply. When you phone them, they drop the phone in your ear.

This is my story. I send a mail to them so that they can change my debit order date to the last day of the month as my salary is deposited into my account on the last day of every month. For the last 3 months maybe more, my internet connection has been switched off, when I phone them and had to wait longer than 10 min to get to a supporting person. I had to explain everything to them and then they switch it back on for the day and it happen again the following day that my connection has been switched off bare in mind the bank charges are coming to me as there are no funds in my acc till the last day of the month. Every time when I have to phone them I do get an " I am very sorry sir" but no one goes that extra mile to ensure that it does not happen again.

In my conversation with the support lady, I requested that they must cancel my subscription and her reply is that I can only cancel it on the last day of the month and that I have to phone them again, What must I phone again? They must be mad if they think I am gone phone them again and again after I send several emails before. I will stop my debit order with them with immediate effect.
