Edgars Terrible Services

I am very dissatisfied and disappointed with Edgars. On the 25th of June 2023 I requested a settlement amount I needed to pay to close-off my account, I then received and SMS from RCS with settlement amount of R2018.44 I needed to pay to in order to settle off my account. I paid the provided settlement amount (R2108.44) on the 25th of June 2023, however few weeks later informed that they made mistake in the settlement amount provided, stating that the settlement I needed to pay is R3560.54 instead of R2108.44. On the 5th of December 2023 I made an immediate payment of R950.00 (using banking details and reference provided from ***) as my account was in arears and needed to pay this amount to bring my account UpToDate to per Edgars. Payment I sent payment proof to *** on the 5th December 2023, however Edgars collections responded on the 23/12/2023 stating that payment is not reflecting on my account. This very disappointing service Edgars which is affecting clients credit scores. Can someone at Edgars assist with this issue as matter of urgency.
