poor customer service and empty promises

took out a Telkom contract in August 2017, phone was delivered early October but something was wrong and i had to return it. After hundreds of calls to Mondo i finally got a replacement phone in February 2018 and was told that a new contract will be drawn up and the previous one will be canceled and i will be reimbursed for the months i payed on the first contract. I have made another call to Mondo about 3 weeks ago to query this once more and i was told a call was logged to Telkom to cancel the first contract. I had to go to Telkom to get my daughter a sim card and i was told by the lady that there is no such request on their system!!!!! made me think, but still today i am paying for two contracts that i was promised by a Manager that this will be sorted out in February already!!!!!!!!!!
