Not getting deposit back after line cancellation

I app**** for an ADSL line from telkom in Jan 2015 but had another current line with another ISP that was in the notice period to be cancelled which means I had to apply for a new line and then cancel the other line which I then did and Paid a R700 deposit for the new line.<br> Once the old ADSL expired I went to eastgate store and cancelled the old telkom line. I was then told after the cancellation I would get a notice of the deposit that will be refunded, I just then have to bring the notice into the store and they will release the deposit.<br> I also had a R210 limit on the previous account which they have kept on the new line even though my monhtly premium is R499, so I kept going into arrears and by the time I get the statement there is already interest due. in march I phoned telkom accounts and asked them to adjust the limit, they then made it higher, however when they debited my account they again only took R210 so now I owe more interest again. On the April statement it now however reflects the new limit.<br> On the april statement there is also no deposit refund mentioned anywhere. Telkom please sort this out and refund my deposit asap.
