Terrible Service

I have been due an upgrade 2 month ago. I was contacted by a consultant and did the upgrade telephonically and then I received an sms confirming I would receive the handset in 7 days. 2 months later I have contacted the corporate section for the upgrade as I am already billed for the upgrade and between the courier company and the call centre they have a reference number but no one takes responsibility and no one knows where the handset it. The numerous ref numbers of escalation cannot even be located. I have logged calls on your emails and on the net without any feedback. What service is this of ****************. I have had no option but to now record this on Hello Peter because there is no one who takes responsibility and still have not received this handset. My name is Elizabeth Gropp-Els and my contact number is ********** 811
