Bad customer service!!!

In April I had sent an email with a letter from my company asking them for a payment suspension as the following month i got retrenched due to the pandemic unfortunately. Since then i was still getting their services but they did not make any debit orders to my bank account up until August month end when i ask easy for a statement to settle the arrears, i get a response to say that my account has been handed over. No communication was sent to me from the accounts all this time and then a few days later i found out my account was listed as a default with no communication from them after sending emails to them and no feedback at all.
