AFTER 5 MONTHS CLOSED ACCOUNT STILL GETTING BILLED

Hi i am very unhappy with telkom after 5 months of cancelling my telkom line and still getting billed with final account and sending telkom a email and getting nothing in reply.Good day Account number: *** I would like to find out the amount of R149.70 is billed for final account if my account was closed on the 6th February 2015 at Bayside Mall Telkom Cape town with Reference number given AL***. For what is this amount billed for? They told me there would be no amount billed further. When i phoned Telkom on the 12th of June 2015 at 1 o'clock with Reference number ***5 they told me everything is oky and no outstanding fees are due. On the 2nd July 2015 i got a sms stating that credit of 224.99 has been arranged and will reflect on the next invoice. So according to my knowledge i do not owe Telkom any money as the line was cancelled in the beginning of February 2015. I am very unhappy about this as i though everything was sorted out after 3 times and i still have a problem on the account after the account was cancelled 5 months ago. If you wish to phone me please phone me between mon and thur 12 pm and 12:30pm or 15:00pm till 15:15pm anytime fri to sat
