Faulty Cue returned - false promise of refund - still waiting after 1 month +

I purchased my cue starter pack (which included two pods) at Twisp Store Canal Walk - while setting the device up it was discovered that one of the pods were faulty (this was swapped out immediately). I then purchased two additional pods, However, the two additional pods were faulty as well - one leaked and the other just stopped working when I tried to use it (both were refunded). I returned the Cue to the store as I was not happy that I had as many issues within 10 days. I was advised that they will process a partial refund (they were deducting the cost of the two pods that were included in the starter pack) and was advised that their Head Office will contact me to get my bank details (as refunds can only be done through HO - only every Friday).

This was 14/02/2019 - still NO CALL, NO EMAIL and obviously NO REFUND. (I would have even been happy if I had received the PARTIAL refund - even though I feel that a FULL refund is due.
