Cell C pathetic service.

I have upgraded in Oct 2018 via phone with a consultant. Since end of oct a extra debit order went of my bank account from Cell C which i never agreed to. After numerous calls to Cell C i was helped by a consultant who discovered that i was never upgraded but a extra line was activated for me, she listened to the telephone conversation between me and the consultant and discovered that i clearly told him i want to upgrade!! the consultant then told me that she will handle the case and ask for a refund, the upgrade has now been done but i am still waiting for my refund or someone to contact me and tell me what is going on, i phoned again today asking for a update when i was told that there was never a application for a refund and that she will now send me a new reff number for the refund, i mean really!!!!!!!!!!!!!!!!! how long is this going to take, another 3 months!!!!!!!!!!!!!!!!! my old reff number is: ********** 258, i have not received the new reff number yet as promised. I will never upgrade with Cell C again, after this contract i am switching to another service provider.
