Billing Issue from day one the worst internet company

Good Afternoon I am frustrated with Rain one of the worst service you can get, the billing is a big problem they want to bill me twice a month for R825 and when you ask to speak to a manager they come with stories and tell you it takes up to 48 Hours for someone to contact you because there is only 6 managers in South Africa, so how much complaints is there for them not to contact you. The worst part is I spoke to a agent and he promised me that a manager will contact me immediately but nothing. They are the worst I should have rathered stayed with my previous provider at least I knew that the customer service was okay and the billing was okay it was just the internet wasn't stable. I have only being with Rain for the past 2 months and both months was the same problem the sales agent doesn't tell you that you will be billed twice a month when you sign up and the next month will be the same if I knew what nightmare I am sitting with Rain now I would have never taken them, people I wouldn't recommend anyone to take them And I will take this to the ombudsman because it is a poor service that we receive here, never in my life have a I suffer like that
