Where do I start? At the time of writing this review, I have just sent a six page, A4 sized letter to Centrica, after sending it through email and not having it acknowledged by the case handler, who could not spell my name right or pronounce it correctly. I have been a customer for 12 years with BG and the last 4 years have been a complete nightmare, firstly I KNOW i have been overcharged, someone at BG or my Housing Association decided the tariff I would be placed on???? Then I have had issues with a direct debit and this was sorted out, then it re-occurred, BG were so bad in getting it sorted out the Bank has barred any further Direct Debit Mandates from British Gas. The customer service is terrible, the South Africans, blame the English Customer Service Advisors and then they tell you that things are not actioned because the BG executive does not listen to them, and that they are ignored, that is why the payment plan fails, the direct debits, go wrong and so on. Then there is the engineers, in one incident an engineer visited his attitude towards me in my own home was rude, abrupt, and unprofessional, I wanted to swing for him, no one would tolerate that in their own home. You complain, you are meant to receive a call back from. a manager, that never happens, the calls drop (terminate) the minute you start asking questions that there is no real answer to - especially when BG are at fault. If you can avoid BG with bargepole this is a company that was once great but that is myth and legend, now it is a mediocre company, that charges through the roof (before cost of living crisis) yet there is no transparency, so you really dont know what you are paying for.
