Lancet Accounts Dept! Pathetic!

Lancet Accounts Dept!!! What a joke! Worse than dealing with Govt entities or municipalities!!! I made a payment to them end of July using THEIR QR Code on THEIR invoice. I still get bombarded with SMS and emails requesting payment and I have emailed the POP I dont know how many times. I even called the call centre and spoke to an actual person who promised to "escalate" and get back to me and I am still waiting. I am so sick of this. Why offer various methods or options to pay when you cannot pick up these payments? Useless!
