FUNDS DONT GET REVERSED

I use UBER and BOLT often; money gets debit from my account for each transaction. Should there be a cancelation fee, balance of my money doesn't get reversed immediately, after noticing this, after a period of time that money isn't being reversed back into my account, I've enquired with UBER/BOLT, who advised that BIDVEST is holding funds and will release funds within 2 weeks. This time lapses and money doesn't get reversed. I've emailed and enquired about this. still to date funds not released/reversed back into my account. So, BIDVest hopes we forget and don't pay us back???? I must now keep track of EVERY transaction; the last consultant told me I must send a dispute form for my money BIDVEST isn't releasing back into my account. Day light *******!
