Bad service from my trusted network

I am utterly disappointed by Vodacom's service. On the 18.01.2016 I took my Lenovo tablet to them for repairs and they took it in and then today on the 09.02.2016 I had to go back to them as I had received no call, no sms no communication at all from them regarding my phone. I sat at Vodacom and they could not trace where my phone was then 15 minutes later I'm told my phone has been sitting in the storeroom and it is actually not supposed to be repaired by them but by Lenovo and I was given my phone back and told I should call Lenovo as they tried to call but they were too busy to hold on for Lenovo. I did not buy a phone at Lenovo but at Vodacom now why am I supposed to deal with someone else and why am I told weeks later? Am I really not that important to Vodacom? <br>
