Nedbank Pocket Pos - lost trade

Nedbank Pocket Pos - we notified call centre of an error on Friday 31st July. Call centre advised that they were aware of the error and that there had been other similar calls. They advised us that the matter was being attended to. The problem was not resolved and the fault was again reported to the call centre. Only to be told the same excuse. On Monday morning we called again only to be told that their technicians do not work on a weekend but that they ere addressing the problem. Called again at 11;45 only to be told the same thing. When I queried about compensation for lost trade they said that someone would call me. No one has bothered to call yet (12:05) Very poor refelection on Nedbanks technical capabi,ities.
