Communication failure

I am quite disappointed in the after-sales service care that Netstar provides. I have been trying to assist my 70yr old father in taking over the existing Netstar account from my deceased mother. I have sent numerous emails and have contacted Netstar on numerous occasions and still no progress. The agent which assisted us has not returned our calls. You are quick to take our bank details for a device upgrade, yet no one has confirmed if the existing policy was cancelled and transferred over to my dad's name. At this point, we're ready to cancel and take our business elsewhere.
