lost sfp due to evri delaying parcels has anyone been able to sort this out as I cannot contact EVRI

we have had our prime deactivated due to evri delaying deliveries, gets collected on time but not delivered on time one parcel was 10 days late! I cannot contact EVRI I have tried many times to call them and email and bot chat but never get to speak to a human, can anyone help or have advise how they managed this, we have stopped using Evri now but the next problem will be that we are not buying all our labels through amazon prime if we get the prime account activated again!
