Please bare with me I'm a newbie, although I have used the site for years.

My mobile bill shows that I called this number,0844 2411192 on the 18th April. It does'nt show it as a prmium or landline or mobile number.
I have no recollection of calling it for 29 minutes.
Anyone have any ideas what it could be? :-?

0844 241 1192 is one of a very large number of numbers used by Sky Customer Services. If you are an existing Sky customer and official Sky website or paperwork directed you to call the 0844 number, use Regulation 41 of the Consumer Contracts Regulations 2013 to claim a refund from Sky.

In future, be aware that their 0844 numbers have been replaced by 0344 numbers. The lack of an announcement on the old 0844 numbers directing callers to hang up and re-dial the new 0344 numbers appears to be negligent.

Just to reiterate Ian01's reply.

The general (main) contact number for Sky is:  03442 414141 I don't use any other number to contact them.

I worked for them for a period of time, and we were always advised to give out that number. 

Is the number you called a genuine Sky number as Ian01 said?  Was it on some documentation?

It's worth investigation.  :)
