Attempt to resolve an account query from 2016

I am writing this complaint on behalf of my wife whom have been struggling to settle a dispute on her Glocel account since 2016. She has really had trouble getting through to someone that can actually assist in resolving the issue on the account with regards to data charges for 2016. She was referred to the accounts departments, then back again to the support to provide information and they then refer her back to accounts or legal department. We have contacted Glocell in 2016 and to this day have not had a single response from Glocel representative to provide account details for the charges incurred. The call center is *******. You call, hold for 9 minutes then go to a voice mail line service. This was on 26 Aug 2017 @ 12:23. If I go for option 5 on the voice prompts there is never answer. I have proof of all the attempted call I have made on behalf of my wife as my phone can also records calls. Previous reference to resolve: ********** 2

Please have your legal department or someone with authority and not a call centre agent with limited authorization contact me.
