sprint sucks

so i checked my credit report. i am kind of anal about this since i want to buy a house (someday) and especially now i will need a good credit rating. any who, i checked it and there was a collection from sprint. from 2007. so i was confused- i havent had a sprint accountsince 2005. so i contested the collection and they sent me a letter saying that it was indeed from me and a copy of the invoice. the address matched but the time frame didnt. so i called harvard collections. they kindly explained to me that this was actually from august of 03-which made sense since i changed my service at that time. they sent it to the creditor in jan 04 and harvard collections actually got the acount in 07. they also explained that sprint and verizon automatically send your last bill to the creditor after you cancel or change your services. in my case, i went to an account through work. she also said that in many cases, sprint wont even send a copy of your last bill. what the *&^% is up with that? good news, since i paid the bill, within 30 days, the collection will be off my credit report. thank you. but really. is that even fair? messing up peoples credit and not even giving them a chance to pay the bill. i am sure i never got a last bill from that account. i am good about paying my bills on time. thats something i dont mess around with. any how, ele, sprint does indeed suck.
