Vodacom Musgrave Damaging clients credit score.

Worst experience ever!!! NOVEMBER 2018 I DID AN Application for a contract however I received a mail and sms saying it's approved and I can collect after few hours. When I approached the store for collection, we noticed the phone model was incorrect, the agent then re-did the app and then it declined. However I canceled the entire deal, went to telkom and it was approved in 10min and walked out the store with my new phone. At this current stage, I have a default on on my name due to vodacom and I was handed over for an amount of R109 for absolutely no reason. The agent Siyanda Gumede of Musgrave Vodacom has an attitude and never helped to resolve this issue even after requesting an email from their head office. This is affecting my credit score and I cannot get finance because of this. I was not even invoiced for this amount but have been handed over. Absolutely Pathetic.
