Contract Cancelation

I wrote a review about Cell C a few weeks ago then they decided to get into contact with my husband about the cancelation of his contract and the fact that it still reflects on his credit record that he owes cell c but paid them up. My husband was contacted by a lady named Danielle Abrahams who is the social media support consultant of cell c, she assured my husband she will fix everything and get back to him within 7 working days, it's 14 days later now we still waiting on her to get back to us. Danielle gave a contact number to my husband aswell as an email address we tried several times to get in contact with her but no luck. Cell C just keep failing its customers with the bad services
