3 weeks for an Upgrade!

It has taken 3 weeks to get my upgrade and STILL I don't have it. After a number of follow up calls to Vodacom, transferred between various agents, to finally speaking to someone, who when I insisted on a solution, not excuses, finally committed to letting me know that there is no stock!! Unreal, how does the online upgrade allow an order if there's no stock. Needless to say, my frustration escalated! 2 days ago I was informed by your outsourced courier service that my delivery is on its way!! 2 business days later, multiple calls to RAM, no resolution! With 25 years client service, process and efficiency experience it horrifies me that no-one can commit to a client! Be it Vodacom or your courier company! My bills are efficiently deducted every month, yet my upgrade takes forever! Why? I'm disappointed and truly hope that this gets the attention I, the paying client, deserves!!
