Poor oh so POOR Management of inbound volumes (Customer Service)

5/6 phone calls of hanging for more than 15minutes and then it rings and the phone gets put down in your ear. I am prepaid customer, can you imagine ow much money i have spent on holding on?. Then they say waiting time is 1 minute and caller number 1/2 and then you have to select the options again only to realise you the 1 minute waiting is already on 10minutes. 2 Emails and a contact form and still no response. You have got to be kidding me - wont be long before it becomes a place no-one wants to go to
