Need advice to replace my macbook pro 2019 battery

Option 01 - Getting it replaced from authorised service - They’re quoting it around 55k as they cannot just replace the battery but the whole unit has to be replaced(out of budget) Option 02 - Getting it replaced from local service - Quoting around 15k Option 03 - Ordering form a trusted website just the battery which costs around 8k and getting it replaced at a local service (but not sure how much I can trust whether they’re assembling the one that we give them) Please suggest the right option if anyone has gone through the similar scenario. Thanksss!!
