Truworths not Tru nor Worth it

I am SO frustrated. I've been building my credit score for months so I can buy a house. Before lockdown, I opened a Truworths account to help increase my score. Lockdown 5 happened and I couldn't pay my account because their stores were all closed. I called in, contacted them on Facebook, emailed and even created a Twitter account just to ask them what I should do- but no reply. I have money! Geez! I told you I want to pay you! It was a measly R110!!! FFS Pocket change! These Truworths people went and put me on a negative rating on my credit profile! For missing 1 day???? I've repeatedly contacted them to take it off - but no reply. DO NOT, I repeat - DO NOT open an account with this company. I actually hope companies like this shut down. Terrible.
