Poos service

I have made accudental transfers of funds into my Vodacom account end of November and up until now I have sent 6 Proof of Payments, made more than 10 phone calls and even visited a Vodacom store in person ro request a refund and Vodacom Accounts departments absolutely ignores my request flat. THIS IS SO UNPROFESSIONAL AND SPITEFUL. When somebody owes them money they suspend your phone contract but when they owe you money you have to throw a fit and wait more than 2 months for a refund. Typical South African BIG Coprporation (lack of) service
