Regus review: Deposit refund over 5 weeks late!!

I downsized offices 3 months ago and was due a partial retainer/deposit refund totalling a sizeable £8,271.28. I submitted the refund request 'via the portal', as instructed on 26th July, and was promised funds WITHIN 15 DAYS. I was then later told after chasing that funds had been remitted on 23rd August at 07:08am and to expect them within 5 TO 7 DAYS... Now 48 DAYS after my refund request, 6 support staff and 21 emails later, also 14 BUSINESS DAYS/20 DAYS after I was told the refund had been sent, STILL NO FUNDS! From 25 years in business, I understand that with any worldwide bank there are 2 very simple payment options: 1, ‘same day’ transfer or 2, ‘three-day’ BACS. It is quite clear and evident that funds simply have not yet been sent and I am being led down the garden path! Appalling, shambolic, inconvenient, upsetting, embarrassing, awful, disorganised and disappointing. I find it very hard to believe that someone cannot simply walk into the Accounts department and instruct someone to remit funds by ‘same day’ bank transfer totalling £8,271.28 to our firms Bank Account.
