Disgusting, unfair and Inconsiderate treatment from Metrobus

My son's bus was cancelled without prior notice and after putting money in my son's and nanny's bus tickets, they just cancelled the bus. I paid Metrobus R2000 and they said they will refund us within 7 -14 working days but no money was received, it's now August and they come up with nonsense about the budget, that is not my problem and they're call centre and management are all just useless. This is *****ing from people. I sent everything that was required for my refund, I even sent multiple follow up emails and made multiple calls to people who have been given a script and told what to say and the call centre supervisor does not even want to take my call. I am a single parent and I cannot just give away R2000, Metrobus is a big ****.
