Payments I have made is not allocated to my account. It's been a month

Payments was made and not taken off my account. It's taking Them a month already to allocate my payments to rectify my account. Sent a copy of all payments copy of my ID and my card number and they still can't do their job. This is pathetic service really. I want My account sorted no later than Wednesday the 6th December 2017 you have had since the 30 October 2017 to rectify it. All one gets it takes 24 to 48 hrs to do every time one calls you. Now it's a months. Fix it asap before the 6th December 2017as affect my credit record. Been in touch with a Lawyer taking this further. Been a customer for 8 years and this is the service I get.
