I had great service from the engineer and he fixed the problem promptly. However, when it came to taking payment there was friction between the engineer and the call handler over the telephone and my credit card details were taken several times. The first card I offered was declined - later I found out that this was because the wrong expiry month was being input. After using an alternative credit card I discovered that the payment was taken twice. All attempts to discuss this have so far led nowhere and I am now getting angry because of the promises not kept - no promised return phone call or email acknowledgement- Job ref 5937139, Complaint ref Z9876643.
