BAD Service from Vodacom Call Centre

We have done an online upgrade by calling 135 to upgrade my wife's contract as we didn't had time to go to a vodashop to do the upgrade and the lady told us after completing the upgrade that we will receive the new phone within 2-3 working days. We did the upgrade on the 22nd of December 2019. We have phoned the call centre again on Saturday the 28th of December to confirm the ETA for when they will deliver the new phone, the person then told us that they are still waiting for confirmation of the order, but nothing further happened. On Monday the 30th of December we’ve phoned the call centre again to query the status of what is happening with the delivery of the new phone and this time the lady told us that they are still waiting for confirmation and that someone apparently tried to contact us on Friday but couldn't get hold of us according to their system. There was NO missed calls or voice mails whatsoever on my phone or on my wife's phone on which they said they were trying to call us on. We then tried to go to Vodaworld today on Monday as nobody is calling us as promised to do the confirmation for the new phone and delivery. Nobody as to yet phoned us to confirm ETA of the delivery or confirmation of the order!!!!! They have informed us this morning that someone will call to confirm the order before COB. This is by far the WORST services that I have received form a company like Vodacom!!!
