Worst Customer service ever experienced

Signed up with Axxess for the Rain LTE connection ,service was running fine for about 2 months and then suddenly connection went off with Modem complaining about a Missing/Faulty Sim card. Logged this with Axxess and this is where my frustration began. Firstly was told they logged it with upstream provider (IS) but they have had no feedback from them. I then asked them to please phone and get an update and was told that IS takes too long to answer the phones and =this is the reason they don`t phone for updates but wait for them. I then phoned IS helpdesk myself and call got answered within 2 minutes but was told that they are not allowed to deal with me directly and the call has to come from Axxess. Phoned Axxess again and was told the same story as before. I have asked to be put through to the manager only to be told he is busy and would phone me back ,which never happens. My internet service has now been down for 10 days without so much as an update from Axxess and seemingly they don`t actually care ,as i can see that the case hasn`t even been updated in the last 2 days. I will rather go spend my money elsewhere ,at this stage i even had better support from Telkom and that says alot.
