Very bad service on debits not known or pending

In May 2020 I had 2 purchases that did not do that showed on my account i called FNB they sent me forms pillar to post query was not resolved. I let it go because it was less than R100. Now on the 10Nov 2020 I did a purchase of R35 vodacom airtime it gave me an error at 13:32, I tried again at 13:34 error again. I went to app they have deducted both the amounts and were not credited. I chat to them Emmah said hi only gave her my query and nothing happened. I logged a ***** query they called me one consultant said its pending transfered me one said he can't see it and hung up on me after I explained my query. Every 5 months I gets bad service from all channels of communication yet they insist of using digital tools with no man power to assist. I wonder who else is paying fees and not aware of what's happening with their fees
