Worst customer service ever.

We have recently downgraded our Vox services from Fibre to LTE, LTE was activated 01/05/2023, debit order was sucsessfully debited, but services arent working. Logged a call with call centre on the 4th, it was escalted to a LTE specialist and promised someone will call us back the same day still. Called again today to find out all the agents are again busy, call is escalated again and someone will call us again. And yet not one phone call. Paying for a service we are not able to use. Pathetic service, will cancel my contract and seek for a beter service provider as Vox has no customer service.
