Very disappointing service.

I am extremley disappointed in the level of service that I have received of late. I am due for an upgrade on my contract, and have been trying my utmost best to find out what the process is and how to go about the upgrade. I have been sent from pillar to post, I called customer service, I was then referred to the sales dept, however when calling the number, the number does not work. I have tried communicating via facebook, I was the referred yet again to customer service, the very nice lady I spoke to advised me that she would send an email to the sales dept to contact me, however no one has contacted me as yet. I then found an email for an employee that works in the Cape Town division and reached out to her for assistance, she the forward my email to the customer service dept for assistance, however, I still have not received and form of communication regarding my upgrade.

I have never been late with my payment, each month, it gets paid on time, but to receive such service for an upgrade is disappointing to say the least.
