Sprint PCS ruined my credit

in june of 1998, i cancelled my 2 cellular accounts with sprint. i then double checked that both acounts were paid in full with the local dealer and was assured that they were. from that point on i received no statements until january of 1999 when i was contacted by a collection agency that i had an outstanding debt with sprint, which i immediately paid just to get it cleared up, figuring i would be reimbursed when the mess got cleared up. i applied for a credit card in sept of 1999 and with denied due to the writing off of the debt by sprint. upon finally getting in touch with a sprint representative, the person showed no understanding and would only follow their guidelines and not at all look further into the matter. until now i had given up due to the fact that they are a huge company and i had no chance of getting anywhere but more frustration. i also have been more recently frustrated by sprint pcs in that they seemed to knowingly have put me on a plan that i not only did not ask for but one that they knew they would profit more from. when i confronted them on it their response was that their system only shows the current plan and there is nothing they can do about previous plans.
