Username change help

[BTBC_Spotifies]

I need disability resources for a call help line to manage my username and password change please. Formal or informal it does not matter.

Thank you, Rashad 

Edit: In addition to that any advice on how to verify my spotify account to update my account. Is a problem occurring because I have not verified my email? Is it that simple. IMO you could update servers to adjoin not several pages to follow along to, but to help finance resources for those that need clarification as to why so many steps are needed to support and find help. Thank you for reading these issues as statements and factors of methods of listening and teaching used from this app far exceed any necessary precautions or entailing reason to shed light for correction and comment on other streaming services. You guys are alright. Lol.
