RCS - Huge delays and still no response

I submitted a disability claim against my account on the 29th Jan 2021, due to being medically boarded and no longer able to afford the monthly repayments. On the 09th Feb, I was contacted by RCS and spoke with Rabia re them needing more information (despite being informed that I submitted too much information with my initial application) the additional requested information was submitted within 15minutes of the call. It is now been 5 weeks later and I have had ZERO feedback since then. I have sent numerous follow up enquiries but only receiving auto-responses from a mailbox that I cannot respond to. In the meantime the debit order goes off as per usual, deducting money that I cannot afford to be deducted. All I want is for some feedback on the progress of my claim before the next payment is deducted & hopefully my account will be settled. I understand that Covid19 has affected the way things are being done, but this seems have become the standard EXCUSE used by companies across the board to mask extremely poor customer service, unacceptably long waiting times, etc, etc, etc and we as clients are just expected to accept this while our monies are still being deducted, on time & without fail.
