Poor and the worst customer service ever - Consumer Complaint for Fedex Dar Es Salaam Tanzania

I have been doing with DHL for quite some times now but this one trial with FedEx has been my worst experience ever . These guys won't pick up the call(its either they put a wrong number or they are just don't care) , won't reply an email , won't notify you on any issue regarding your consigmnet . By the time I am writing this complaint its 3 weeks now and I haven't received my consignment. I hope they won't come with any fishy story in the end . I will never recommend this company to anyone here in Tanzania , unless they do some really serious changes in they operations
