Dropped calls from Debt collectors

I owe Markham s due to me being on maternity leave since March just after lockdown happened I paid my account with the money I saved up for my baby but the last 3months I could not pay them due to me going back to work having spent my money on the baby essentials. Bear in mind I am fully aware that I am in arrears and I want to set up a payment plan I explained my situation to one of the many agents calling me in one day dropping the calls when I pick up. I wanted to highlight the dropping of calls because I could not set up a payment plan of I had no income. I returned to work in August I was paid prorata and had to plan my whole month around that minimal salary for August. Get incoming calls from Tfg agents when 8 pick up they drop the call and every month they add it to my account arrears I don't think it is fair... Please manage the calls as I work in a call centre myself but the bar is raised quite high as it is a international call centre and if we drop calls on consumers it's immediate dismissal Please remove that phonecall charge from my account because I'm not speaking to anyone at the end of day...
