Poor Poor Poor feedback

I logged a complaint on 23 March and was given a reference number ***. Till i have had no feedback and now i must start calling the call centre where clearly no one know what is happening and no decision can be made. I am paying Bradlows every month without fail. The least they should is get back to me and give me feedback. Unless nothing is done i will have no option but send my complaint to Peter Griffiths the group CEO, i am sure that he will do something about this.
