Pathetic service from Standard Bank

For the last few days, I have been phoning ***, to corfirm my home loan repayment amount. Did this to make 10000% sure of the amount. Every time and every person I spoke to said that my amount is R x. I phoned on the 15th,17th (twice). The persons even said that the new amount with the interest hike will only go off on 20 November 2022.I even used the self service portal on that number and there also confirmed that amount. So, something just told me to phone again this morning. Now,this morning I spoke to 3 people who said that the installment is R x. Not the original amount that was given to me everyday. This after everyone said that the installment will be R x and confirmed it. All of them said that they will get someone to call me back within the hour, and it's been more than 3 hours since my first call. This is not my fault as I have done everything I can as a client to make sure that everything is in order according to the information that was given to me. I budgeted for the amount that was given to me every single time! The service from Standard Bank and their home loans department is just pathetic and no one wants to help and at least give feedback.
