Totally Incompetent

I held Sharesave accounts through my employer paying in on a 4 weekly basis, in June I was made redundant and afer being given incorrect advice by Computershare advisors was told I could make a further 6 standing order payments into each of the 4 accounts I had running and then use the option to by the preagreed shares. However the total lack of knowledge and incompetence of staff have lead me to overpay into the the sharesave accounts and Computershare are now not acknowledging the overpayment amounts. Have tried to contact on numerous occassions and they will not transfer me direct to the department I need to speak to so they either put me on hold, never to return or simply hang up. The advisors are uncaring, uninterested and lack knowledge, they appear to follow scripts and if your query is not on their list then you get cut off. I have never been treated so poorly by any company ever. Avoid at all costs.
