Unresolved query. Pathetic customer services

I went to FNB branch on the 28 th September 2021 to query a deposit which I did, and unfortunately I lost the receipt so I needed proof of payment, I was assisted by the FNB personal who took down my details to query it and I asked by when will they get back to me, the reply Thursday. Today is the 1st no correspondence received from them. Thank God I don’t bank with them unfortunately had to use their services, which is so pathetic
