I think Shopper's World closed when the British Woolworths shops were sold off by their American parent company & their new buyers decided to rationalise their operations.

The department store city centre shops and Woolcos also had gone by the mid 1980s.

The theme to Are You Being Served? mentions a telephone department, I assume department stores could act as agents for the GPO / BT selling alternative telephones & it would still need qualified engineer it install them.
