So as you mentioned you had not yet submitted the visa applications nor had any interviews, which means you should get a refund as the submission has not yet been processed by the home office.
According to the UK government website, you can either call or email to request your refund, and you should get a response to say they are working on it in two working days, which you did, and you should have a result within 28 working days.
Since you applied for the refund two months ago, that could fall inside the 28 working days (public holidays and weekends not included) therefore they may still be working on it. If it is outside the 28 working days then after an extra week or so you could try getting back in contact with them about this using the following info:
By phone: 00 44 203 481 1736 (Calls cost £1.37 per minute on top of your standard network charges)
By email: Follow this form (Email enquiries cost £5.48. You will not be charged for any follow-up emails about the same enquiry)
