Lack of service delivery

I have had nothing but terrible after service from Vodacom ever since I have upgraded to contract. The device was delivered without a Sim card, I called customer service immediately after delivery (Tuesday 24/10) requesting for a Sim to be dispatched. I was assured that the courier will deliver it that same afternoon, Wednesday 25/10 I called enquiring about said Sim delivery and it was once again promised to be delivered that afternoon. Thursday morning I once again called and a sales agent informed me that no Sim was dispatched as no order was logged for said Sim. At this point I am beyond frustrated as I have been asked security questions, put on hold so many times and transferred from one consultant to the next just to be told nothing has been done. I spoke to a supervisor who advised I go into a contact centre as the soonest date for a sim delivery will only be the following week. I did that, left work early and went to a contact centre. I paid for a contract sim and was promised that a sim swap and rica would be done and the sim would be active within 24hours. Well today is Tuesday 31/10 and I am still not able to use the new device as the sim swap is still an open/hanging order ever since Thur 26/10. Vodacom has sent me from pillar to post and yet they cannot help me. But do bear in mind a deduction for this new contract has been made but I cannot use the service. Vodacom I would appreciate it if you could for a change give me a call and TRY at least TRY and deliver a service to a paying frustrated client. I feel that most of your consultants are *********** as I have spoken to more than 15 of your consultants of which none of them could explain this mess.
