I submitted my application in October, for 10 December activation

I submitted my application in October, for 10 December activation. The line was only activated on the 20th December. During this time no one at Homeconnect could provide reasons for the delay, except for passing the buck. Even the escalation process was unhelpful. Once my line was activated, I first complained on the 21st about poor speeds on my 2.4ghz line, after numerous calls again, the issue is still not resolved. I am paying for a 50/50 line but the 2.4ghz line cannot even provide 5mbps. Extremely unhappy, as I have been a loyal customer for almost 5 years.
