Warning: Mr D is absolutely useless after they have your money

So I have placed numerous email complaints to Mr D Food regarding @iCides that become invalid and my credit being voided for no reason. Then I'm told that the void was done so I could reuse the WiCode which is **** cos it doesn't work. Eventually they tell me to ask my bank why the WiCodes don't work. How the heck can I ask my bank why Mr D Food's WiCodes don't work, this is completely idiotic. Mr D Food Support is absolutely useless and if they IT specialists, they should stay where they are cos they don't know what they are doing. I give up because I can't stress over idiots who don't listen or understand. Simplest solution, don't use Mr D again.
