Why does Telkom not respond

I have spent over R200 on several telephone calls to Telkom to apply for an internet line. I was told that I must pay a deposit of R700 and they would SMS me the details for this deposit and it must be payed in 7 days ... it is now day three and I still have not received any details to pay this deposit ... I have tried several times to call but after about 15 minutes (R25 per 15 minutes) there is still no answer or the call is just dropped. I am applying for the January deal and by the looks of it they are trying to make it difficult for us to apply so that we don't get the deal ...
