Hi Divya,
First, get rid of the immigration consultant.
Your consultant has made mistake after mistake in filing your mom's TRV applications.... contradictions in information, length of visit, strong ties, purpose of visit (from the first application itself), etc.
The mistakes are pretty evident.... nevertheless, do order GCMS notes. With three refusals, it looks like your mom may not be able to attend your wedding.
Do not reapply without addressing the previous refusal reasons + with better paperwork. If you reapply, it must be after several months.... when her situation changes significantly. It is going to be very difficult to get a TRV approval
Don't lose hope though
EDIT:
You're also facing the risk of misrepresentation due to all the contradictions in documentation/evidence.... do NOT reapply until several months after you get the GCMS Notes.
The last thing you would want is your mom getting a 5-years ban
