what started off well ended

what started off well ended so badly.. i Was in the process of purschasing a property through this agent but the staff and service provided by almost all at the darley street branch was below standard from the way they answered the phone the tone and manner in the speech how they handle the customer requires some serious customer service training needs. After my offer was accepted a third party / second buyer was also interested in the property which is fine, fair and expected so the offer soon increased by £20k and instead of drawing a line anywhere and letting one of us start the mortatge process i kept getting asked for my 'best and final offer' which was asked over 7 times in the space of 2 weeks so i told them if its a bidding war they wanted they should go for the auction route as best and final offers are asked once and the highest offer gets the property but this is becoming a joke how can i sort my mortgage and start paying for fees and surveys when they keep on agreeing to other offers after accepting mine.. which was supposed to be the 'best and final offer' i was at my wits end and only 1 agent from the this branch was helpfull and brilliant at her job 'Keiran/ Kiran' unsure of how her name is spelt but this lady was polite well mannered had fantastic customer service skills at all times kept me up to date with whats happening apart from the 4 days she was on sick leave.. during them 4 days the other unhelpfull/ unprofesional staff had given me incorrect offer amounts.. i got 4 people to call up and check exactly what is going on and all 4 came back with different amounts from £109950, £125000, £128000, and finally £115000..? these were all the supposedly current offers on the house so anyone offering would have to offer in the excess of these that is what the agents at whitegates told the people i got to call up and enquire, so when i received the call the follwoing week asking again if i would increase my offer of £121000 i explained what i had found out and teh agent on the phone denied all this to my shock i explained i was present when the calls were made to their office to ask what the current offer on this property was and the agenst gave all 4 callers 4 different amounts i told whitegates that iam retracting all my previous offers i am not going to put my time effort and money and trust in a company that has messed me around for 4 weeks lied been caught out and not had the decency to apologise, managed to speak to 'Keiran/Keiran today who was very apologetic for the way i had been dealt with i informed her that i will be writing to head office about my experience and why in future i will not be using whitegates for buying, selling, letting or anyother service.
