They call me 3 or 4 times every day and have done for weeks, yesterday I reported them the Ofcom and called them yet again to ask them to stop calling then they called again yesterday evening and again this morning! I have again reported them to Ofcom and have again called them insisting they stop calling me. Even if I did have any financial compensation due (which I don't) I would never employ a company who push their business on people so aggressively.
