Excellent to horrible in a second

Previously I have had only exceptional service from L&M. One of the best stores to ship in, in fact we spend hours in this store each month. Today I have had to deal with the unbearable pain and experience of having to enter your birthday competition. Why do I need to send an sms to a number only to be sent a link to go online? Is this a plot to make money from these messages as well because that is extremely sneaky and as a company you will lose my trust if this is indeed your intention. A simple link to visit initially would have done the trick. Now after going onto the link, I discover I need to enter my loyalty card number. As a consumer who carries very very minimal cards, I always provide my mobile number and your staff are able to locate my profile, why can't this be the case for the competition as well? Your receipts don't make mention of my loyalty card number yet you expect me to carry this card on my person at all times. Please guys how can I move forward if i don't even know where my card is? Do I lose out on this competition because of a failing from your company to be all inclusive? Lastly your newsletter makes mention of dealing out mystery in store DIY gifts each weekend, I spent a little under 4hrs in your store walking each Isle carefully yet received absolutely no gift. Please explain once again if a back needs to be broken before you keep to any word without a ploy to make additional money from consumers.
