I have no electricity since yesterday

I have no electricity since yesterday, I phoned BCMM electricity call centre yesterday and I was given Re****711 and I was informed that my account is up to date there must be some fault with electricity but their electricians didn't arrive to investigate. When I phone them again today with aforementioned ref no they informed that the ref does not exist and I was allocated another ref no.49822, I have been waiting since yesterday they have not arrived up to this time. It is needless to mention the inconvenience I suffer because of this poor service delivery.
