Most frustrating customer service ever experienced! Pathetic service

I have been contacting Directaxis for the past few weeks to get a settlement letter, I eventually get the settlement letter and do the payment, now I'm struggling to get the paid up letter. Spoke to a consultant yesterday requesting this letter and this morning I received a statement which is 3 months. I understand all companies need to adapt to a new way of working due to COVID-19 but customer service should be a priority. Apart from the phone calls I have sent numerous emails with the proof of payment but no response received. This is really frustrating and by far the worst customer service or help I received, after many mails and calls I still don't have my paid up letter. This is unacceptable, disappointing and frustrating.
