Paying for a service not provided

For the past 5+ years I have been paying for an ADSL package that guarantees minimum bandwidth of 4MB - and I have had numerous line outages and never had a speed higher than 3MB. If they cannot provide a service then they should not sell us the service in the first place. <br> <br> They keep promising that they are upgrading our area, but after being patient for years now I am considering legal action to get my money back for all the years I have not had the guaranteed bandwidth. <br> <br> There is no way to get hold of people in decision making positions because there are no names, email addresses or phone numbers either on Telkom's websites or from the people answering the phones at the call centres of even the Telkom stores. Nobody that we can hold accountable and get answers from regarding when these issues will be addressed. <br> <br> In addition to this my line is often down and lately it takes a Telkom technician 2 weeks to show up once you log a fault.
