Unfair treatment

On the 30th of December 2017 got a call to state my pricelock contract is coming to an end,I asked that if I renew my contact for another 24 months and get a new Explora that my price will be R959,I was fine with that since I was previously paying R899 and R35 for insurance that equals R934! Nhlanhla did a credit check and stated minimum requirements not met! I can't accept this, my credit record is clean -never had defaults, been paying by debit order and never has a debit order bounced, work at the bank and ITC clear, earn R50000 per month and extra income of R40000, dstv wants to tell me I can't pay amount Of R25 extra,please check ur records again as this was a slap in my face as a loyal customer, Hennie Coetsee and email is **********
