I hate yall

Like i said ,I Hate this people now..not the brand ,the useless billing team, i refused to reply to em coz i think the only reason they fixed my issue that day,is because i came here nd wrote a review..i paid on the 24th of jan ,my payment date is in the 25th, this people send me a notification that i owe R500 today(the sec of February) nd im suppose to pay R500 due on the second of February,how the f has it already been 30 days????
