Nick Culley, product marketing director at ADI distributor Midwich, revealed sales activity at ADI had significantly reduced during the last six months/
"There is no focus from [ADI] and we have had supply issues for some time. In some cases, we have had to switch sell to Teco and Samsung because customers will only wait for so long," he claimed.
"I have not received any answers from ADI about its plans for next year and I am very disappointed," he added.
One industry source suggested communication between the manufacturer and the channel had been poor because staffing levels were at a bare minimum.
There were suggestions that of the 20 employed at the start of this year, only three remained.
Another source stressed: "I haven't seen an account manager in months and stock levels have been diabolical. I don't think [ADI] wants to stay in the UK market."
Martin Kent, UK and northern European sales manager at rival CTX, confirmed it had already talked to resellers seeking a viable alternative to ADI.
ADI refused to comment on the situation.
