Paying for 2 internet speeds on 1 line

<p>I migrated from a 4mb/s uncapped to a 10mb/s uncapped DSL line. After numorouse calls and visits to Telkom shops, Telkom charged me for a 4mb/s home uncapped line and a 10 mb/s home uncapped line on 1 phone number? I tested my internet speed for about 2 weeks and the best I got was 4.2mb/s. I reported the line as faulty a week ago and nothing came from that. When I called today the sales department cancelled my 4mb/s uncapped package and resetted the password for the 10mb/s DSL line. The internet is working now, but I was billed for 2 uncapped packages that is not fair. </p>
