They took my money for masterguard they didn't apply on my order

CIELO at design quarter Fourways. My experience there has been horrible. I bought a mattress, headboard and base and paid for the master guard. The delivery did not come with the master guard certificate as per usual. I tested the items to ensure that master guard was done and found it was not done as per guidance received from the store. It is clear master guard was not app**** on my items and have been in contact with them for 4 days now demanding my money back for the master guard. They are giving me the run around and all I want is my money. I basically paid for a service that they didn't deliver and they have no shame to keep my money with my service. Terrible experience.
