<p>A case was opened regarding my query on the 6th of june. On the 15th of june i then receieved an sms saying my case has been resolved.</p> <p> </p> <p>I called in on the 19/06/2017 and the agent told me that they tried to contact me and my phone went to voicemail no changes have ben made to the incorrect billing.</p> <p> </p> <p>I need to understand something... because you could not get hold of me you close the case without it being resolved..... disappointed!!!</p> <p> </p> <p>Please note that i will reverse the incorrect amount should this not be resolved before my debit order goes off.</p> <p> </p> <p>i can not be going through the same process every month.
