Telkom offers Contract then Declines it ?????

Telkom Contacted on Tuesday 28/11 to upgrade my LTE Contract (Account number ***) to a Fibre contract It would cost me a R100 more a month , I did agree to it , Yesterday morning I got a message , I didn't pass there Credit Check , so don't qualify for the upgrade ( Ref ***A ) which in my personal opinion is ridiculous , I have been a customer of Telkom for many years never missed a payment I have also never missed a payment with any other service provider in my entire life , I have a Clear Score Credit Score of 710 / 740 I assume this is a decent score . If anybody from Telkom ever reads this , you have my account number please contact me to inform me when my contracts expire as I would prefer to take my business elsewhere as you don't seem to want mine for which you originally contacted me.
