Billing problem, suspended account soon

Good day Rain

Again I'm stuck with the system you put in place leaving me with no answers or solutions towards my problem. Since my last review and request to change my billing date to the 1st of every month rain keeps on deducting my monthly billing on the 25th of every month. After I called and called to assist me this problem keeps on going. Im left again with debit orders going of at the bank with feeds attached to that I'm told to make the payment and change the date again. I'm afraid to change the billing date cause rain couldn't assist me in the first change I made. Now as Im writing this rain are going to suspend my wifi and this may cause jobs to be lost as for we in south africa cant afford this. If this happens im forced to close my business with rain and seek other business that will and can support there customers in this regard. I'm a paid customer and supporter rain with all my communications held in your hands. I hope that we can resolve this and are not left in the dark after this complain.
