POOR/NON EXISTANT SERVICE FROM MERCANTILE BANK

We are new clients to Mercantile Bank. We did not know how to download the proof of payment and called into the call centre on the 1st March for assistance. After 30 minutes on the phone the consultant could not assist us. He assured us that we would receive a call from a colleague early on the 2nd March. We did not receive the promised call. We also sent a message on Mercantile's website on the 1 March 2021 asking for assistance and giving the reference number. Now on the 3 March, two days later we have still not received the call that we were advised that we would receive first thing on the 2nd March and have not had a reply to our website communication where Mercantile says that they will contact us "SHORTLY". We are wondering what Mercantile's “SHORTLY” is, so that we know for future reference. We have learn, in our short relationship with Mercantile, that they over promise and, not only do they under deliver, they do not deliver! We do not think that this will be a long term relationship!
