Horrible Customer Service

I wrote a review on my invalid voucher experience on 19 January 2018. The feedback I got from Edgars was: " The customer services team will be taking note of your details and we will be sending you SMS communication regarding this in the next few days". Since then I got no feedback from Edgars although they said they would be in contact with me. It is now nearly 2 months later which is not "in the next few days".

I decided to call the customer service to get feedback on the issue after two weeks of no feedback. Each time the customer service promised me that I will receive feedback within 2 days from the marketing team but I never received any feedback whatsoever. This process happened to approximately 8 times (Which you can gladly verify on your call service system as you log all the calls). The last time I called they couldn't even give me an estimate time frame that this query would be resolved in, and in my experience the customer should query otherwise it will just be ignored and fade away. How long should I be patient? How long should I wait to follow up on my query as there seems to be no communication between Edgars and their customers? My personal opinion is that a query should never take 2 months to resolve? Please advise me what to do next. My reference for the previous query: ********** 2268/GO
