Horrible Service

I recently settled my account with Cell C and I have sent a request for a settlement letter since the 20th of January 2022, I received an automatic response saying I will receive feedback within 48 hours. I called Cell C to ask for feedback on 24 January 2022 and I didn’t receive any help, was sent pillar to post but still nothing. I called again on 1 Feb 2022 and I was told to wait a further 48 hours. I can’t wait any longer I want my matter resolved as a matter of urgency.
