RCS ITC (TRANSUNION) INFORMATION UPDATE

How long should it take a creditor to update the the ITC status? It has been a little under 3 weeks since I made the payment for my debt to RCS and my records at transunion haven't been updated. I made the payment on Octber 14 2020 and I haven't had a response to date. I've had a series of telephonic conversations with RCS in trying to resolve the matter but in vain. Can I please be assisted with the clearance of ITC status as this has put my life to a complete halt. I have sent the proof of payment together with the settlement letter to RCD and MBD and nothing has bee done so far.
