Still no approval or contract

I app**** for a contract with Telkom Kolonnade on Tuesday and was informed this afternoon that it has been app**** due to a low credit score. I don't have much debt and have accounts that have debit orders monthly. The lady that dealt me the news, told me I must bring a letter to reapply but on questioning as to what the letter must say, she didn't know. I then wanted to speak to the owner of the business as the staff is *********** to deal with the situation but was told that they cannot give me the owners number. I have app**** for a adsl contract last year already and it was approved, but upon installation it was found that there was no infrastructure, Telkom didn't even offer any service to me. I now would like a 30gb LTE package for R499 per month but this was declined. I was told by the Telkom staff that I can buy the modem/router from CNA and can then buy prepaid bundles @R899 for 20gb.Thats almost double for less data and now I must be discriminated against if do it on prepaid. I want a 30gb package for R499 per month on prepaid or Telkom must give me a contract. This is a essential service to me and one that I desperately need. Please help Telkom.
