Query and refund as promised, outstanding 2 months later!!! Emails unanswered

My last review of Europcar was on 20 Jan 2020, relating to an impossible fuel charge (tank was filled 300m away from drop-off) as well as Europcar not addressing my queries for over a month.

A month later and the customer service is worst than ever! On the 28 January, Team Leader Thuba Nkomo ,promised me a refund which would reflect after 4 business days. Subsequent emails to inquire about my refund go unanswered.

As S.Africans we tolerate unacceptable levels of customer service , but Europcar is certainly the worst I've experienced, and they don't seem to care.
