Other (i.e. phone, health club, etc.) False statements or representation Attempted to collect wrong amount Georgia

the collection company contacted me with - % debt reduction offer for payment if made by -/-/2016. I sent the check that was dated -/-/2016. they contacted me again on -/-/- ( after a whole month ) to say that they have not rcvd the check on -/-/- but on -/-/- hence the - % offer is not valid and they are requesting the remaining - %. Also, the collection company did not report to credit bureau that i paid the - % or that by their offer that dept should no longer exist. since I did n't send my check via register mail, it 's their word against mine. i did try to reason with the person i talked to that 1 day should by acceptable for error margin but they refused.
