Bad customer service over my refund

I have been trying to get my deposit back after I cancelled a purchase on 22 Aug 2017 . I have sent emails numerous times t. I have furnished E-Engineering with the documents that requested. I've since been told that my request has been forwarded to finance department, its been 2 months that I've been waiting for feedback. when I call, I get a message that " my call cannot be taken at the moment"., It can only mean that you have blocked my calls, i fact I have established that fact. I mean how then to does one negotiate with the company and come to a settlement agreement if they do not respond to your emails and block your calls. I practically cannot get hold of anyone in the company. Are you suggesting that I use platforms such as Hellopeter, claims court, magistrate court, high court to actually communicate with you over my money ? It is clear you have very little regard for customers and effectively your growth as a company.

I plead with senior management to assist me with this matter and lets settle the matter amicably please.
