Worst service provider ever.

Last month our phone lines was ******. We logged a fault and after a week of no feedback we phoned Telkom only to be informed that they are not going to replace the lines. My husband then ordered a new modem with a sim that was supposed to be delivered in 3 day. Every time you phone the call centre they give us different feedback. From no order to the modem has already been delivered. yesterday my husband went to pick the modem up from the courier service that was supposed to deliver it. Guess what no sim card included. phoned again and was informed to go to any Telkom shop and get the sim. Went to the shop and now they can't assist as it was an online order. Worst of all after having no internet the last month, we were still billed and the installment was deducted for the credit we have due to over paid installment as we never get a statement. What now!!!!!
