Appaling service

Worst ever! I took a month to month contract on a LTE router due to waiting for fibre availability. When I cancelled the contract with one month's notice as per the conditions I was billed the month after the cancellation period had run out for another month as well as a cancellation fee. I disputed the additional month and after a lot of interaction with various employees it was taken off my account.

Some time after that someone phoned me to arrange collection of the router which belongs to Vox. Vox organised their own courier to collect on a certain day, the courier arrived and I handed over the router and myself and the courier signed the waybill that it was collected on 14 April 2021. Since then it has been an absolute mess, I received an invoice for the router some time after it was collected. I explained to various employees that the router was collected by the courier that Vox organised and sent the waybill as proof. I have been receiving constant emails with the router invoiced to me and that I must pay it. I am not liable for this, I handed over the router to the courier and have the waybill as proof. If it got lost between the courier and Vox then IT IS NOT MY PROBLEM. But to get someone at Vox to actually understand this is near impossible and to get hold of someone in accounts telephonically is impossible. Yesterday I received a FINAL DEMAND LETTER from Vox and if I do not pay this I will be handed over to a collections company. I had to get into my car and drive to the Vox 3rd party agent who assisted initially with the contract to go and ask for assistance as I do not know what to do anymore. I refuse to pay for something that I am not responsible for. This is not rocket science but since the router seems to have been lost after collection from me it is just easier to hold the client liable for other parties incompetence and mistakes. I reply to all parties included in all mails explaining the situation but any feedback from anyone is non existent. I will never ever do business with Vox again nor refer anyone. If this issue is handed over for collection to another party and affects my credit scoring I will legally pursue the matter further.
