Poor service

I contacted Tekom call centre on Thursday 15/09/2015 requesting my usage for the month. The lady promised it was sent but I never received it. Secondly, I app**** for another line but was declined due to my credit score being too low. I have had my current contract for for more than a year and it has always been paid on time. Why can't I then take out another contract with Telkom. Once my contract is finished I surely will be finished with Telkom too.
