Cellc deducting funds twice a month from my account

I have been with Cellc for over a decate and no problems until I had to change my debit order date in December 2021, which I informed them in Jan 2022 to change it back to 25th of each month.

Issue now: 1. In December 2021 called in to change debit date to 8th and then informed Cellc to change it again to 25th...Cellc had their December payments. 2. In Jan 2022 on 8th and 25th cellc deduct funds 3. In Feb 2022 on 8th and 25th cellc deduct funds 4. In Mar 2022 on 8th and 25th cellc deduct funds 5. Now In April 2022 on 8th cellc deduct funds Note My debit date is 25th not the 8th but still it falls no success. This above injunction with several calls I have made to cellc to fix the issue and it was promised to me issue is resolved but to my disappointment issue still persist.

And for a normal consumer that just just makes ends meet it is tough to still pay my bank chargers and on top of it Cellc adding their panility fees on an issue that is not even my fault. I would want this to be corrected as soon as possible and this is not my fault to pay panilties when i have dine my diligence of informing Cellc to correct my debit dates. I believe all calls are being recorded please review each call to evaluate who is at fault.

Will I be compensated for the past few months that I had to pay bank panilties and those of cellc. I feel as that I have made necessary arragements to change debits dates in due times and issue was not resolved at cellc and its unfair towards me to pay for panilties where I was not at fault.
