ADSL down for 10 days

We have on numerous occassions reported that our ADSL line is down and not working. We have received multiple reference numbers, the latest been the escalation number S203780 (original reference number was 1228CRK200215). Call centre managers promise to come back, but no follow up. Promises of a technician to come round but conspicous by their absence. Name of technician is Eric Mabundza. Call centre managers not contactable as their numbers do not work nor do they come back (Jaycelan Rangasamy and Felicia Maraisa). it was escalated to Bradley Slinger at detect specialist depatment. He has not come back to us. We want service restored and to be credited for downtime.
