Pathetic Service

Absolutely pathetic service!!! I have a credit note on one of my accounts and have logged numerous calls, spoken with 6+ consultants, sent in email proof on 11 & 16 August (to vcontractor people), including "pop" as per request and all I ever hear is "it has been escalated"!! I am still waiting for a Manager to call me back, as confirmed by 2 consultants. As a loyal customer for more than 20 years, their service is not even ratable - useless and a waste of time and energy to deal with.
