Used to be a good service
Rebel recently started charging a fee to top up Zimbabwean numbers. A 10usd top up used to cost around £7.70 depending on the exchange rate. The same now costs a fee of £1.47 meaning it now costs £9.20 to send 10usd which is far worse than the exchange rate. This is daylight robbery. The website still states this service as fee free. Their support is non existent and you get answered by a robot.
