Rude call centre, did not receive token, waste of time

Initially seemed like a convenient way to buy electricity without leaving your home. However, I bought electricity today and after an hour still did not receive it. Call centre, over 10 mins waiting, no answer. Called again, to be in contact with a very rude man. Very displeased with lack of efficiency and rudeness, eventually got the token but will discontinue using this method and advise others not to either.
