Regus review: Return of part retainer

I requested a part retainer on 3rd January after downsizing last year, which was acknowledged by email. I am still waiting for the refund after many excuses and over 2 month's delay.
Where is my money? My account number is. (8308169)
I have already complained several times and been fobbed off at local level, an IT problem, a Glitch, a query, looking into it etc etc. the company is still taking my monthly fee, no problem there.
This is a really poor example of customer service to a loyal client of 8 years good standing...
