Bad Service from Sheffield Beach Villa

I booked accommodation at the Sheffield Beach Villa for 8th June 2018 to 11th June 2018 in October 2017. there was a lot of correspondence between my self and Amanda. When we reach an agreement I payed a portion of the deposit to show that i wanted the accommodation and stated that i would pay the balance shortly. I had forgot about the balance of the deposit. On the 28th December i received an email saying that i did not meet my side of the deal and it has now been given to someone else.

I called Amanda to apologize as i missed an email from her dated the 27th October requesting the reminded of the deposit.

I was told by her that im unprofessional and she will not assist me. I responded informing her that a simple phone call to remind me would have be nice and appreciated to which she rep**** its not her responsibility to call me, i should have called to arrange a later payment.

I find this unacceptable
