Bad service from Vodacom Online

I have cell phone contract with Vodacom and was due for upgrade now in November 2017 . Vodacom Online service agent contacted me by the name of Wendy Naidoo on the 8th of December 2017 to sign a new contract via the phone, WHICH I DID . Everything was fine and I got the phone Samsung Galaxy S8 + a Top Dog Educational Voucher of R10 000 on the 12th December 2017 and the telephone agreement with Wendy Naidoo was that they will give me a R5000 flight centre voucher which never transpired . RAM couriers came and delivered my phone on the 12th December 2017 , In the box was my Samsung Galaxy S8 . Later the even I open the box and I picked up that there was blue dot on the screen and seems like a factory fault . On the 13th December morning I phoned Vodacom online and advised them that there is a factory fault with the phone and Ashley Leonard assisted me and logged the complaint and advised that the phone will be picked up and new phone will be provided . I received a call from Wendy Naidoo on the 14th to ask me what the problem was and I explained to her what I told Ashley and she told me the exact same thing that it will be picked up but nothing transpired . I then phoned numerous times to ask when will they will pick up the phone and was told they follow up with RAM couriers but nothing came of it. I then phoned on the 18th December and insisted on speaking to Wendy Naidoo senior which was Sameera Chetty at VODACOM online services . Sameera Chetty promised me that she will contact RAM couriers services to collect the phone from me . It ist the 19th December today still nothing . I phoned VODACOM services again I tried get hold of Wendy Naidoo or Sameera Chetty and I was told that the both are not in the morning and then wanted to speak there senior which was Craig and he is not in ,

I then was put through to guy who was very helpful by the name Eucebius and he advised me that this should have be dealt with long time ago and it should have taken them 2 days to pick up the phone and delivered a new phone within a week . According to Eucebius no pick up was logged for the phone. I am sitting with a very expensive phone which I cannot use because of the fault . VODACOM online service is really bad . There is no service . I am sitting with new phone which I cannot use for more then a week and no one at VODACOM seem to care. If I get ****** or the phone gets ****** because I have not insured it as yet I will be held liable for the loss .

It is the 19th December 11h50 am and no contact from VODACOM .........
