Poor Service

I have an account with Aramex Global shopper. Wow, the service is really horrific of late. I joined there Flex program over December, but I am getting charged the incorrect shipment fees. When I query the fees, I first get asked for proof of payment of the Flex program. It was an online payment, - surely they have proof of the transaction. Further to this my accounts says I subscribe to Flex, so what gives? From a delivery point of view I am told that they attempted to deliver this Moring but no one was home - yet I was home all the time. Supposedly the tried to call, but I have no missed calls! What a disappointment!!! and I still don't know when I will get my packages.
