Mobile phone retailer Phones 4u has closed its 362 stores, with the loss of nearly 1,700 jobs - including the Mansfield store in the Four Seasons Shopping Centre.
Six out of its eight employees were made redundant and the store is earmarked for permanent closure.
Two employees have been retained in the short term to assist with the closure programme.
Phones 4u had an annual turnover of £1 billion, with more than 700 stores and a total of 5,596 employees.
But the firm collapsed as service provider EE pulled out of long-standing deals to sell devices through the retailer.
EE said it would buy 58 Phones 4u stores in a deal saving more than 350 jobs - which include the store in Idlewells Shopping Centre in Sutton.
Rob Hunt, joint administrator and PwC partner said: “It is with much regret that we have made the difficult decision to close a large number of stores.
“It is a very sad day for the staff working at those locations and our thoughts are with them.
“We will make every effort to help the affected staff, working with the Phones 4u HR team over the coming days to support employees.”
