Telkom can not honour its promise

For the past 2 weeks my ADSL internet connection was intermittent but I could still use it with great patience. Since Tuesday (26 May) It has been down more that it has been working. I reported the fault on 26 May via internet (using my mobile data sick) and was informed that the fault would be fixed within 4 days. Today is the 4th day with not a Telkom technician in sight. So much for their promise of 4 days, Since I upgraded my ADSL line to a supposed 10 Meg line and 50 GB data I have be stranded without an internet connection for most of the time
