【正确答案】Dear Mr Opik I apologise for missing your recent call concerning your new pool. I was also sorry and surprised to hear that you have experienced problems with it so soon. As you will recall, when we originally discussed the question of heaters, I presented to you various options. Some were smaller heaters, others were more powerful. Clearly, different people have different tastes in how warm they would like their swimming pool to be. Consequently, at the time, I advised you to buy one that you thought would be best for you. You chose a smaller, less expensive one. I am sorry that you are now regretting that choice. As a result of this, we feel that it is not our responsibility to compensate you for a new heater. However, I do sympathise with your situation and in order to resolve this problem, I suggest that you ask the manufacturer for an exchange for a bigger heater. Generally, they are quite good about this sort of thing and should give you a full refund on the original heater. If you like, I would be very willing to come and give my advice on which heater I personally would put in. This visit and advice would be free of charge. I hope you find this solution acceptable and look forward to hearing from you. Yours sincerely Selma Chakrabati
