Angry customer

Mondo called me on the 15th of May 2018 to offer me a rooter on behalf of Telkom, which I told it was delivered on there 1st of June. I called them after reveiving the rooter and they said it will work once it's registred, I called them on the 4th of June and they said the number is registered I must remove the sim card and put it back again after 30 min which I did but is still didn't work. I called them on Tuesday and spoke to Tia who kept on putting me onhold for more than 5 minutes, she said it's not registred but she is sending a request for it to be registered and she will call me or sms me. I haven't had anything from them since, I tried calling today and I am put on hold again for more than 5 minutes while they going to check and verify my profile. Their call center people are very rude they don't listen but qiuck to talk back to customer. I asked to put through the manager or team leader and they said non of them are available. I spoke to Bafana today who said he will send an email for reactivation and I was told the samething yesterday. I ask to speak to the manager and know 1 available today again. Their service is very bad no 1 is willing to help me and they have already deducted R99 for administration. I want to be refunded my airtime that I use to call them, I feel cheated by Mondo they sold me lies. I don't recommend them to anyone.
