Accounts department bad reflection of company

After two visits to a store, countless phone calls, from me and store staff, to emails with all relevant information, truworths account department staff seems either unable to read, or does not have the mental capacity to screen an deposit list from their bank! It can not be the responsibility of me the client, to do the job of employees I am already paying with my purchases. More than send proof of payment, send email with explaining how to look for a deposit WITH ref no, calling one cannot do. Account department is dangerously unqualified to handle payments, and that might be falsely reflect badly on ones credit regord SHOCKING!
