Always escalating to higher who-ever! No results..

Received a new phone with new SIM card. New SIM card has a new number which I did not request or ask for. They promised to transfer my old number back to the new SIM. After 6 phone calls over 2 week period, nothing. NO response. ALWAYS escalating to who-ever. Not phoning back. No email correspondence. NOTHING. So... for almost 2 weeks NO customers or clients have been able to get hold of me on this BUSINESS line. Not a personal line. Every-time I phone, I have to speak to a different consultant. Every-time the same... I've had it with Neotel.
