We . The company is Tunit have been with talktalk for around 5 years. We have come to change to a cloud system and leave talktalk. Our new provider kept trying to port numbers but talktalk kept rejecting with no explantion. Despite employing our new provider to organise this i called 3 times myself to cancel and port numbers. The first time talktalk said our new provider had to port the numbers to close the account. ( this was not true). The second time was not assisted at all . The third time and only when i asked to go through to customer services did they tell me they kept rejecting the transfer due to an overdue balance. The balance at the time was only its normal due balance although after a month of not being told anything by talktalk was 2 months due. Customer services told me they could not tell our new provider that we needed to clear the balance to close the account and port numbers. So in other words they just kept rejecting it. They then tried to put the onus on myself saying if i had called them they would have informed me. This was not correct as i had called them 3 times and only when i asked for customer services had they told me of why they would not close the account. They also spoke to my new provider numerous tines and could have asked through them for me to call. They essentially on 18/01/21 told me incorrectly that my new supplier would close the account instead of asking me for the balance which if they had i would have happily paid. I disputed what customer services were reading from notes and asked for the recordings of my 3 conversations with them. They said they would listen to them and come back to me. They have not come back with the recordings but instead come back and said they will carry on billing my company until we clear the full balance. I will not be blackmailed due to poor service received and address this fully with Ofcom. I received uncooperative emails from Zoe in customer services. Michael Bromley Tunit (BVS Ltd)
