Poor Service from Autopage for a client of 18 year

I upgraded my contract April 17 2015.Asked for a Blue Samsung Handset.<br> To date I still have not received my new handset but my contract has been Provisioned as they term it.<br> Monthly charge for handset is R305 .My question is -how can I be charged for a handset that Ii never received.<br> First I was told stock in the week of 21 April then early may then 18 May.<br> My monthly data bundle was tampered with without my instruction.<br> Emails are ignored.When submitting an enquiry on line on the website they mention feedback within 24 hours or sooner.Later you get receipt of your query and then it says in next 7 days.<br> To get hold of Management is almost impossible.<br> My last communication with retentiosn consultant was Tuesday 19 May with promise of feedback by next day.<br> To date my emails ignored and telephone number just rings.<br> <br> I have been a loyal client for over 18 years and deserve better servce.<br> I humbly appeal to speak to a senior manage who can assist me.<br> <br> Thanks
