CUSTOMER WANT TO PROCEED VIA CALL

I do understand that you wish to finish this via phone as it is more convenient for you. As much as I'd love to phone you, but my tools are only limited to chat support. I can also assist you with your query on this conversation and be assured that we'll do our best to help you on this matter. I can also provide you our TalkTalk phone number if you'd prefer a phone call.

How would you like us to proceed?
