Reversal of funds IMMEDIATELY

This bank has caused too much financial inconvenience for me. I confirmed several times if this person doesn't have a Tymebank account to send them money. When sending them money for a voucher, it says the cellphone number is linked to an account. When i called the call center, they tell them they can only give me feedback within 24/48 hrs but does not guarantee me receiving my funds. Tymebank needs to adjust this immediately as some people do not want money to be sent into their account, but instead sends it straight into their Tymebank Account.
