vodacom never responds

Vodacom website -\My vodacom"is down so often I am unable to consistently utilise the site. I have 12 linked numbers and I use my primary number to manage the others. The other numbers manage SMS devices and their operation is vital to my business. I have had other complaints before and I am given reference numbers by customer care and told that I will be contacted within 24 -48 hours this never happens. I am never - NOT ONCE EVER contacted. it is pointless getting a reference because I never have the situation resolved or am I ever contacted. I again phoned this morning and after being unable to have a satisfactory answer I asked to speak to a supervisor - not one was available and I was promised the only one available was busy on a phone call and she would return my call as soon as she was off the line. This must be a very long call (2 hours). Vodacom I cannot say your response is inadequate because that would imply that there is a response."""
