Wrong Billing

Annoyed with home choice Calls for arrears account, i paid my account on the 4th May 2015 for April month and also on the 19th May i paid for may account which i was supposed to pay on the 25th so now i am receiving lots of annoying calls claiming that my account is in arrears, i paid in advance and i paid more than the instalment now i have to pay interest for up to date account.<br> <br> secondly i bought items telephonically and i was offered R250 discount by the consultant but when i received goods and statement i was overcharged and no discount was allocated i called them more than 5 times and my issue was not resolved even today.
