Pathethic Service and query resloution

On the 31/12/2014 my parents had moved residence from Verulam, Durban and to their knowledge they were unaware that they needed to give a 30days cancellation notice period to their Telkom landline. Thereafter my dad had went through to Gateway Telkom to place cancellation to the landline facility on the account number ***. He had spoken to Anesh which confirmed with my dad that cancellation is done. By the 31/01/2015 my parents were under the impression that the landline has been cancelled and no longer active. To their surprise the account in \arrears"was handed over to Prudence at Telkom accounts management. Fees and the Telkom landline usage had accumulated from January 2015 until July 2015. They had been contacted and requested several times to make payment. My parents being ages 70 & 60 years could not understand why this payment was requested. I ( Larisha Ajodapersad) then got involved to get resolution from Prudence. I had requested for her Supervisor/Manager (Rena Reddy) to explain and resolve this issue. My parents have been summons to a 24hour payment. This matter was handed inappropriately by Prudence being disrespectful to my parents and lack of communication."""
