Extremely poor service and incorrect information

I called to sign up for the DSTV Explora premium package over 3 weeks ago. In the 1st week I spoke to someone who took all my details and did the credit check and confirmed my account was active and I would receive my decoder in 48hrs. By the end of the week I had not had any phone calls or arrangements for delivery of the decoder so I called again. I escalated this time to a manager, who called me back only to tell me that I was supposed to send a text message to a specific number for a consultant to call me and do the final piece of the verification. This was not communicated to me initially. So I sent the text and someone called me at the beginning of the 2nd week. I was asked for further details which I provided and the consultant informed me that my account was now active and I should receive my decoder in the next 48hrs. Again by the end of the week I had not heard anything so I called and escalated again. This time I was told that my banking details had to be verified and I needed to provide documentation to complete this process. Again this was not communicated to me in any previous conversations. I have since provided the documents and still do not have my decoder week 4
