Branch and call centre dont speak the same language

So about 2 weeks ago I did an application online for a loan and they called and did the affordability check and that went well they told me I qualified for a certain amount and that all I need to do is submit my docs in a branch and that it will be done and I wouldn't need to start from scratch and If the person at the branch gives me an issue i should tell them to call the head office.So I went to the branch and was told that they need to submit my docs to the head office.I explained to the lady what I was told over the phone but she disregarded it and continued to take my docs and send them to the head office.Then she said I entered my second name as my surname,fisrtly my phone auto fills and I hardly use my second name so I would have to manually fill it in.Secondly I was very bothered that she ddnt ask if I used my second name she just assumed or insinuated that I did.but anyway she told me that they will get back to me with regards to the loan and that in the meantime she will fix the naming errorr.5 days pass and no feedback so i call the call center and I am told that its still pending and that i need to go to the branch again which really i dont feel like doing so here I am at the branch luckily with a different assistant but she tells me that it has to be rejected coz of the naming error and now I am annoyed then the previous lady who assumed that I cant spell my name comes out of nowhere and tells the assistant that is helping me that it indeed needs to be cancelled so here I am doing a brand new application on a Saturday when I should be watch series and stuff.
