Belvoir simply stopped returning my calls after I left the place I was letting from them. After almost two months I've had to open a dispute with the tenancy deposit scheme in order to try to recover my deposit. They never even asked me for an amount of money, so this felt quite ridiculous, but in the end trying to get them to engage with me was just too stressful. Be wary of trusting them with your business, because they clearly don't have any respect for their tenants' time or money.
