Charges for call divert to UK mobile

[Brenda113]

I diverted all calls from my landline to a mobile (on the O2 network, although my bill says it’s T Mobile). I pay £3 a month for the service. In addition, I pay for the diverted calls.

The question is, how is the cost of the diverted calls calculated?

For example, if I don’t answer the diverted call I’m charged 52p with the connection lasting approx 4 seconds. I assume the call is charged as a full minute at the standard call charge of 24 ppm. That leaves an additional 28p but I can’t find out what this is for. Any thoughts?

I’ve searched the website but I can’t find an answer.

It could be that the voicemail message kicks in regardless of whether anyone leaves a message?

If I take a while to reach my landline, it goes pretty quickly into that mode and probably records up to a couple of minutes, before cutting out.

Yes I spoke with a customer support manager before I posted here. Apparently the charges looked correct at her end. She also suggested it may be answerphone messages that increase the cost, although I had no messages and, if someone was leaving a message, how would the cost be determined if the duration isn’t recorded.

Yes, I took a quick look around the advice pages and it's not at all clear, @Brenda113. 

I'll move this to the billing section for you, though, as it's not actually a problem with the phone working if you have set this up for your own convenience. 

It is possible to add a boost which would limit the damage every month. Especially if you can get the boost added at a discount.

Nevertheless, it would still be useful to customers generally to know where this more than double price is coming from!

Doesn’t seem to be down to voicemails. I didn’t receive any messages matching the dates and times of the 4 second calls.

But, in any event, calls that I know I answered, lasting up to 1 minute, are also charged at 52p. So I think there there must be an extra charge over and above the standard call rate. 🤷‍♀️

Are the calls going through to Voicemail?

That could account for costs clocking up, @Brenda113, even though you didn't answer.

Staff will respond after the weekend.
