bad service about DSTV & ON THE DOT PARCEL SERVICES

I currently have a very bad experience with my DSTV Explorer being delivered to me by the courier services "On the Dot Service Centre". 27 March 2017@ 11.26 I received sms's from DSTV that my Service Smartcard has been activated, also an email that I do have my DSTV Explorer on hand, whereby I realised that there must be a mistake as I did not receive my DSTV Explorer. but i recived parcel from on the dot which was from WOOLWORTH online services and lady from jhb who place the order woolworth online and already paid for it. i have to got woolworth and get the details of that parcel which ON THE DOT delivered to me instead of my dstv explora parcel. when i contact the lady she said she still waiting for her parcel from tuesday 27th nov. When I I contacted DSTV, whereby they refer me to "On the Dot Service Centre". I contacted the courier services, whereby they mentioned that the parcel was delivered and signed by someone, and that they will have to investigate as to who received the parcel. I also contacted DSTV to report this matter, but thus far no-one could inform me as what will happen. My question is why is the parcels delivered to the wrong receipients, as you have to display your ID as well as the parcel reference number OFT1T ********** 0. but the person who came to deliver parcel ddnt ask for identification.pity part that they delivered woolworth parcel which is order placed by lady from jhb that same woolworth parcel they delivered to me on my tracking no which dstv provided me. Also I am now trasferred from number to number, but thus far no one could assist, not DSTV, nor On the Dot Service Centre. This is a very unprofessional services rendered, as now I am paying for something I do not have.
