Thanks, you have answered what I thought.   Well they have now lost me as a customer.   I am with another provider also on a work phone and they never do this.

Have called me a couple of times now. They do claim to be Vodafone marketing, but are not very professional in there calls and assert some strange things. I am not convinced they are realy Vodafone reprasentatives. Possibly phishers.

I got a call from this number and they wanted me to upgrade my existing Vodafone mobile plan. They quickly asked me for my date of birth, which I declined. I wonder what other personal information they could have asked me and what they could have done with this information. Quick and pushy sales tactics.

Got a call from this number. No voice message left.

I have had about 10 calls from this number above and am sick of it!!!  They never leave a message either, so it is very suss.   I know no one in the 07 area.   I don't carry this phone with me, but see the number come up when I check for messages.   Is it a telemarketing company / vodafone perhaps?   The calls come in at all times of the day.   If it is Vodafone then they are a nuisance.  I'm changing the number soon because of it.

Its vodafone marketing
