Lack of service

I ordered a cell phone online and it was delivered on the 17th January 2019. I tried to activate it the evening and I got a "No connection" error. I went to a Telkom store the following day where they confirmed that it was an OBF and that I should log a call to have to phone collected. I logged a call the following day (Saturday 19 January) and they informed me that a Telkom agent would contact me on Monday to arrange for collection. I followed up on Tuesday 22 January since nobody contacted me on Monday and was informed that there was in fact no call logged on Saturday. The agent then logged a "new" call on Tuesday 22 January 2019 with the following reference nr. ********** 2 and was promised that it will be sorted out shortly. On Friday the 25th I went to the Telkom store again to follow up a I was struggling to get through on the customer service line. The assistant manager emailed them on my behalf to escalate the call. Today is the 11th February. I received a invoice for a phone that I am unable to use. I tried to follow up this morning and when I finally got through the call was dropped. I am utterly frustrated with the service or lack of it that I am receiving. Hope the matter will be resolved shortly.
