Terrible so slow

Ybs Initial aip took 2 days to be processed by the underwriter then when they called back to say it was approved I changed to 5 year fix had to wait another 48 hours to hear again they said it was ok. No one was available to complete the form that day so they said they would get someone from the branch to complete the next day. No one called the next day so I called they reported they had an appointment arranged for the day after. Finally they called on Thursday went through most of the info again.

The form was not recieved till tues posted on Tuesday 12th with the information they requested and was told I could pay by card after it was recieved. Initially no one could locate the envelop but eventually found however I was told I was unable to make a payment as the system wasn't set up to take the payment for 24 hours. I called the next they had to wait another 24 hours before process. I was told next I needed another 8 forms of evidence which could of been highlighted prior to posting the application. All information was provided now I was told it would take another 3 days to process. Called back 4 days later still be processed but had outstanding information required. I phone back to check this was received. This was then sent to the underwriters so another 48 hours as although the rent of my buy let covered 150% of the mortgage the amount paid into my account which takes into account repairs and fees isn't 150% sooo frustrating.
Process so far has taken nearly 1 month.
