Annoyed customer

On the 15 January 2019 I received 3 sms messages stating that Lancet Laboratories has handed me over to ITC-BA and Bayhack Landau Collections with the following references WH ********** and WH ********** . I called the number from the sms and it was an agent from ITC. I provided the reference number WH ********** and the agent didn't have that reference, so i provided my ID number. The agent stated that the account was paid. That really annoyed me beacuseI paid that account in September 2018 already. So I didn't bother calling the second number because I was irritated with the fact that the 2 statement of accounts I recieved via SMS on the 14 January 2019 don't indicate the payment of R1000 I made on the 08th January 2019 and a payment of R2000 made on my behalf around Oct/Nov 2019 for Ref WH ********** .

I really don't appreciate Lancet making me look as if I'm not paying my account and they don't have their ducks in a row. I got a call from one agent with a statement that doesn't include the above mentioned payments and that made me wonder how these accounts are handled when they don't show on their agent's side. It's really annoying to deal with Lancet really.
