telkom not delivering

On the 14/11/2017 i app**** for an upgrade handset on the company cellphone. we have signed & e-mailed all the necessary documents and have received confirmation from Nu Molefe that the phone and mi-fi router would be delivered to us by the the 22 November. We never received the phone or router but were subsequently advised by the courier on the 24/11/2017 that the phone had gotten lost in transit. No one from telkom has contacted us & on numerous occasions contacted them to get feedback and we still have received none. We urgently need this phone for our company and we need the router for business operations and we now have had to utilize a staff members router to operate. This is a great inconvenience to us and most frustrating is the lack of feedback from Telkom and the bad attitude we received when contacting the call centre. number linked to this query is ********** 482
