Cross Roads — service on wheels - service issue

Address:

110096

I now regret taking the service on wheels service from crossroads rsa. I have been trying to get a service done from them from past dec'17 and have raised the request twice on the mobile app, spoke to multiple helpdesk guys, sent numerous emails - but nothing!!
Excuses#1-the service mechanic have the equipment with him at his garage, but for not door-step service.
Excuse#2-mechanic's car just got broke down, so he wont able to come
Excuse#3-service engineer wont be able to come to provide service, but can come to pick up my vehicle to his service centre!!

Their helpdesk team at phone are pathetic. Dont know anything about the company nor about the services.

One thing i am pretty sure about is that their auto-reply mechanism works perfectly. As i only receive auto-reply emailers whenever i write to their email address.

Whom to escalate is what i want to know and how can i get my refund back which i have given for the service?
