Am very angry and tired of homechoice

I wrote to hellopeter in June about my homechoice account. They called and pretend to fix my account but it's back to square one again. Homechoice is ill treating its customers o feel sorry for old people as they do not check their statements. I am paying my account by debit order but now anthen am told that I have an overdue amount and this is affecting my credit score... I lost 17 points in a months time because they are failing to fix my account and remove the incorrect billing. The agent can't even explain where the overdue amount is coming from as my account was paid on full before o started buying again last year. I can't want to leave home choice and I will never recommend them to any one shame... They are *****ing customers.
