i want this account closed!!!

i have been a loyal costumer at homechoice and i was paying very well until in november i forgot to pay. one of homechoice consultant called me and we made arrangements and i was gong to pay (900 which was double the amount) in december which i did. paid it on the 31 decemder 2014. early january they called me again asking me if i did pay and i told them that i did but somehow my payment was not reflecting on their system. after repeated phone calls they finally told me to fax them the proof of payment. only then i was told that i owe R80... i paid 90 and i thought i was done paying. only to find that i still owe about R3 which increased to R5 as time goes by. finally in march i paid R10. SURPRISINGLY INSTEAD OF HOMECHOICE OWING ME RIGHT NOW I OWE HOMECHOICE R1.62. THIS IS GETTING WAY OUT OF CONTROL. another thing now when i check my credit record homechoice is blacklisting me. i would really appreciate it if they clear my record, clear the outstanding amount and close the account. need more improvement in customer care! <br> dont know what to do... please help
