So annoying! This happened with our sols when we bought our current house. I arranged everything, dealt with all the communications. Most of the purchase funds were in cash and most of this from me personally. They knew this as I had to make a series of transactions from various isas and savings accounts.
A couple of weeks after the purchase they sent a letter, addressed only to my husband, enclosing a cheque, payable only to my husband to refund a surplus sum on their client account WHICH I HAD BLOODY PAID IN THE FIRST PLACE! I sent a scathing email saying how appalled I was, which they ignored! I was also appalled by that as I am a solicitor myself and we have to open a complaint file for every single complaint we get, properly acknowledge and deal with it. I gave up pursuing it because the stress of renovating the new house and working full time. I regret that now.
Also last year, booked thomas cook flights, paid with my own personal credit card, listed myself as lead passenger, gave my email address as contact. 48 hours before boarding passes emailed to my email but with the greeting "dear Mr [Husband]" and to add insult to injury he was now lead passenger! I did snigger when they went bust five weeks after the holiday. though we actually missed the flight anyway
Oh, one more! Had new windows put in the old house. Salesman said he'd be back with samples to make our final choice. Didn't return. I rang him to follow up and he said the windows were already ordered. (I think he made a mistake and panicked but no excuse for the next bit ...) He then told me "oh I spoke to your husband and that's what he wanted". Turned out to be a blatant lie obviously but I'm amazed that he thought that would fly! Gaaaaahhhh!
