BAD BAD BAD SERVICE!!

Finchoice has been harassing me me for the past weeks. Phoning me and asking me to pay account in arrears. When I ask how much and how come because my account is a debit order ? they not sure, it might be a balance that was shortpaid - what the hell?. I get 2 to 3 call a day during my working hours from them and I keep on telling them that I m not on arrears. I receive a statement stating a 0.00 arrear - but they wont stop calling. I m so sick and tired of them!!! Can they do their jobs properly!!! everyday I get these calls from different people. the last person I spoke with told me it was an error on their side , she will fix it. But she didint because I keep getting the irritating calls. <br> PLEASE STOP DISTURBING me . This is sickening!!!
