3 weeks since Ive been told to expect delivery within 72 work hours. Still nothing.!

I app**** for a new Vodacom contract on the 10th of Jul. and the application was accepted with reference number ***1. On the 12th of July I received a sms stating that the package has been collected by the couriers and that I can expect delivery within 72 work hours, tracking number K***. On the 15th of July I sent an email to ram couriers to folow up on the delivery because the link in the sms, that I received with the tracking number, opens up a webpage that that says "something went wrong" and "we cannot find the page or deal you are looking for". I didnt receive any response from the couriers and on the 16th I phoned ram couriers only to be informed that they've sent the package back to vodacom just earlier because there was apparently no suburb specified on the delivery note and that theres nothing they could do. I asked why they didnt phone to confirm the delivery adress if they were unsure and the response was "I dont know". I was then told that I should contact vodacom and was given a number that does'nt work. I then sent an email to ram's customer complaints but again didnt receive any response. I Then sent an email to the agent that assisted me when I app**** and he responded saying that he would send it again and that it would be delivered the following week. On the 18th as well as the 23rd I sent mails to follow up on my order but didnt receive any response on either one of the mails. On the 25th I sent a mail to Vodacoms customer care but as with all the others mails I've sent, I didnt receive any response. On the 26th of July I phoned Vodacom customer care and was redirected to sales who then redirected me to after sales and all I was told is that the order was cancelled. seeing that it was Friday afternoon I decided that I'll continue to try and sort out my order the following Monday. Monday the 29th of July I phoned the agent who assisted me and I asked him why I have not been getting any response on the mails I've sent, he apologised told me that he has been very bussy. He then assured me that I will receive my order within the week and I received an email with reference number ***4. The week has passed and I have not heard or received any feedback on my order. This has been a real unpleasant experience so far and I feel its completely unprofessional. What is the function of a customer service if no one attends to it? Its not acceptable for any company to ignore their customers especially a company as big as Vodacom. I've been patient enough and will no longer accept the poor service that Ive received. Its been 3 weeks since I was told I'll receive my package within 72 work hours and Ive not received a single phone call or email. I use to work in sales and I'm blown away by this level of service. I dont expect to be treated as a vip but I'm still a customer. I want my package delivered as Vodacom assured it would be.
