Phones4u, part of UK phone company The Caudwell Group, was left without a retained agency two weeks ago when four-year incumbent Brazen PR resigned the account - the agency said it identified a conflict of interest after winning a contract with network operator T-Mobile in July.
Phones4u marketing and PR director Jim Slater said the chain, which has 350 stores across the UK was now reviewing its options ahead of the three-month campaign in the crucial end-of-year period.
'We are still looking at our consumer PR needs but we have talked to a few agencies as part of that review,' said Slater.
'We decide on the next step before Christmas.'
Speculation around an £800m sale to UK market leader Carphone Warehouse led the group to call in financial comms firm Smithfield last month.
As well as Phones4u, The Caudwell Group owns fixed-line company Caudwell Communications, which includes residential phone brand Homecall.
