Lancet call agent cut the call on me

Received a call now 4 Nov 2025 09:36 from Lancet about an outstanding account. I questioned why the amount was so high when last year it was around R500 to complete payment. Now its R1500 when i queried this the lady looked at some other portal and said oh yes i see R560 something. I was upset as to how they change the amounts payable if i query it. Then i asked her to explain as i did not care what systems are being used, what is the amount that i need to pay today because i was asking for the link to make payment but she cut the call on me. What kind of customer service is this from Lancet when you want me to make payment. I told her that i had made previous payments that had not reflected hence the delay in payments however she has no idea why i have different amount. And cut the call on me. Get your service in order Lancet and some who knows how to speak to customers please call me to advise next steps. Highly irritated!
