Lancets pathetic accounts department.

I paid an outstanding amount at Lancet Ruimsig after being notified my medical aid paid short. Since December 2023 I kept getting sms's telling me I haven't paid. Each time I phoned the accounts department.. each time I sent proof of payment and was told there were backlogs in the allocations department. But acknowledged receipt and told me to ignore the sms's. They kept coming I kept phoning and was told all is good ignore them. This has been going on since the end of November begining of December. Today I have been notified that I have been handed over to debt collectors. So I phone again and am told the problem is I must send the proof of payment as a pdf not a screen shot???????I paid at there offices with my debit card the screen shot of the bank transaction has all the info why now after nearly four months are they saying this. The time date date amount account no everything required is on that screenshot why wait untill they hand me over to tell me they need a pdf file, after all this time and two to three phone calls to accounts every month and nothing about a pdf was ever mentioned. As it is a shot of my bank account how do I convert it to pdf, and more to the point why should I have to do this. May be the press should take a look at this as looking at hello Peter reviews of Lancet, I am one in thousands that have similar problems. Devi are you listening?????????
