I had a full service to rid of Bed bugs I brought for a holiday, Spray + Heat treatment, that cost nearly £1.000. When I came back after the service I noticed my carpet was damaged in a pink color, I've contact the customer service who advised me to use a local pound shop carpet cleaner which will remove easily. I've tried myself many time and could clean up, they send them someone to do another spray session and clean the carpet with a professional cleaner machine. Didn't work either. Then asked me to look up 2 different quotes for a patch repair, I got 5. 2 of those informed the patch repair wouldn't look good considering the type of carpet, other 3 just have provided the price. I've shared that concern of patch repair may not be the right solution and asked what they think about that, that was the answer: "Being honest, in my history of dealing with carpet repairs, patch repairs will blend in providing they are done by a carpet specialists. You will find carpet companies may disagree with patch work as its cheaper and they would rather make more money and sell a whole room of carpet, to add if they knew a company was paying for the carpet they would always go for the more expensive option." Then, they chose the cheaper one, asked for my bank details and asked if I would draw a line in the matter if they send me the amount. I was naive and confirmed. They sent the money in 2 days. The guy came to do the service and advised me the service would not look good for the position of the damage and type of carpet. So I should replace the whole carpet in the corridor for a decent result. When I emailed JG Pest Control saying that, they came back with we have drew a line, the provider saw the picture and etc. I understand their point and I have in fact drew a line in that matter, but seems unfair to me to assume the extra costs (about £120), not even considering the time consuming this is taking. Long story short. They may damage your house and not be fair to fix it properly. I assume I was naive and hope you don't need to pass through this. Good luck.
