Adsl Vdsl upgrade

After upgrading to Vdsl a month ago TELKOM decided to switch my line over to Vdsl eventually, Friday more than a week ago. I still don't have adsl or vdsl and all I get from customer care every second day l phone is a escalation promise and a new reference number. How many times can you escalate a fault. My adsl was working fine, all they had to do was switch my existing adsl line over to vdsl????
