no Service

On Dec 5th I bought data time for my ipad but got the message ' no service\<br> I phoned 111 six times on Sunday - as I presume the call recordings will show<br> Of the six times <br> Once the call dropped as it was transferred<br> Three tiimes I wasn't asked any security questions<br> Twice I was asked but once the person's accent was so bad I couldn't understand the questions and in the end the system locked me out. She said I must call advanced data and gave me the number but guess what- they aren't open on Sundays<br> The next call I made some progress but the call was dropped- nobody phoned back although they obviously have my number.<br> So the next ( and last ) time I called I said to the person "if this call gets cut off will you call me back on this number\"" ' \"" yes will do\"" he said<br> Then the call got dropped and two days later I am still waiting for him to call me back and I still don't have any service <br> Then I got diverted to the system that asks you to rate the service !!!!!"""
