Frustrated customer

I have never seen a business that does not care for their customers like Mweb. I have been complaining for almost a year now about their poor connection and nothing has been done but they debit R624 every month without failure even though the do not provide their services, i have called them counteless time and still no solution and when i want to cancel they say i must pay a penalty for something that i do not use but pay for every month.i regret the day i signed up with mweb
