The poorest service ever received . After years of being using PimlicoPlumbers unfortunately the last expirience has been a disaster and not digestable. They were aware of my issue with the plumbing system as they have worked out several times on this. Fact is that last month I called them as I was experiencing a new leakage from the shower ( same issue that they fixed back in June), the engineer showed up, not longer than 10 mins, he realised that it was due to blockage of the system that required a professional drainage not to the fault of the underneath switch. Billed the full cost and insisted to book the drainage service for the day after, something I always carried out with a specialist drainage company in the past . The following day a new engineer showed up, without any clue about what was the issue, took time to understand what I was supposed to do ( while it’s a recurring service I run twice per year and based on the previous notes the engineer is fully aware of the issue and how to address,it takes not longer than 1.30/2 hours) Funny enough he spent five hours, he billed 5 hours regardless my shocking reaction and on top of that he did not fixed any issue. When he left I realized that the whole bath/kitchen system was still blocked and it was not draining properly to such an extent I took pics aas evidence and booked for the day after the drainage specialist company that sent out a very expirienced specialist and tbe issue was resolved in less than two hours . There is a job report stating what was the state of art: apparently not job or very limited and poor job was carried before . Net net, regardless I have been a loyal clients for years, that the issue of my flat was well known and easy to address, I have been charged for a full call ( 10 minutes follow up ) and for a ridicolous 5hh/1000££ for a routine drainage work that was not carried at all, or totally wrongly and poor executed . Then I had to pay the other company on top Almost 1500££ full cost vs average 200-250 usually paid . Even more unacceptable the early response from their customer service than arrogantly and inappropriately keeps denying the refund and affirming that they did everything professionally,regardless the formal concerns of the engineer who carried out the work and clearly admitted that the job was not done asking me not to escalate the matter but offering to come back again This is totally unacceptable for a company like PimlicoPlumber, and this is my first complaint ever filed and first negative review written in ages. I cannot accept primarily the customer service attitude, and their dogmatic refuse to consider the matter the issue the merit complain and the genuine frustration of loyal clients,by denying any evidence and third party report
