Vox in the lead again for most pathetic service of the year for a Telecoms provider!

Yet again, it seems I need to write negative reviews about Vox until I actually receive feedback from them, after numerous calls and still hitting a dead end! I returned the faulty UPS on the 7th September and one of your consultants confirmed my account would be credited for that issue as the UPS never worked and it took over a month to get resolution and paying for a device that didnt work. To date, my account has NOT been credited! I called on Monday and enquired and Lerato from accounts said she will escalate as they cant see that I returned the UPS. Now I have a form that your Vox consultant signed confirming they have received the faulty UPS on 7 September! I called again Wednesday to follow up and i was told the credit need’s approval from my accounts manager Alessia/Alyssa - not sure - and that she would call me before the end of the day to confirm everything and process the credit It’s Thursday 10.30am and I have still not received any calls or emails from this lady and I need to process my monthly payment before you fools block my line for your lack or ownership in getting back to me and resolving this query. Like what does it take to get some good service?? Do we need to light a firecracker under your chairs to get you guys getting back to customers asap?? The service is just shocking!
