Worst customer service I have ever received

After being told that it would take 7-14 working days to activate my fibre line and internet connection with Supersonic, I cancelled my previous internet contract feeling confident that given the worst case scenario (14 days) I would have internet to continue working from home. Worst mistake I could have made.

A technician came to connect my router, but left without securing internet access- saying there was an issue and he had escalated it, and that someone would be in contact with me. No one contacted me, so I called support and raised a case on the 7th of May, and have called daily thereafter for assistance but am met with different excuses from customer service reps and the techies - neither of which are able to tell me why the PMO has not contacted me in 10 days. Eventually I requested to speak to the manager and was told i would be contacted by them within 48hours- to no avail. Follow ups and escalations with the PMO is no longer enough for me as it leads nowhere- I want timeframes and reliable communication- neither of which has been provided to me.

All in all, some of the worst customer service I have ever experienced- I would not recommend supersonic to anyone.
