I requested for an Engineer on the 9th of April and he came in to check my electric boiler (Pulsa Coil - Gledhill Electric) . I mentioned to the company online during the booking process about the make of the boiler. The customer service lady mentioned that she had an engineer to come in on the same day and he did come to check the boiler. The Engineer mentioned to me on arrival that your company/himself did not really support this make of boiler but he was very pleasant and said he would try and do his best. He did work on it and we had hot water again briefly for the short period he was here . Within 30 mins of his leaving, the hot water became tepid again and became lightly cold again and back to how it was working BEFORE he worked on it. I only noticed this when I tried to take a bath shortly after he left .. I paid 102 pounds for this service. I called the your office to report this and there appeared to be some confusion as to why and if the issue with the Boiler could be resolved as clearly the boiler still remained unresolved as there still was no hot water. I was informed that your company could send me an Engineer that knows how to work on my type of boiler and I would have to pay for this service again if he is to come out. My question is why should I do this if your company clearly knew the make of the boiler before sending the initial Engineer when I booked the initial appointment. Why then did you send me someone that was unfamiliar with the make of my boiler and still charge me especially that the boiler still was not working properly? when I sent an email to your After Sales team, I was informed it would take within 7 days to investigate my complaint and get back to me? This is unbelievable.
