I pay for an annual service/maintenance call due Feb.20. Unfortunately due to covid BG could not attend. Rang end May regarding this visit and told would be coming. Rang again June and said when was my maintenance going to happen as I could smell soop. They took the details and stated the costs, I said that as I had a contract they was no costs. Long story short I received an invoice and maintenance visit was not carried out. The story goes from bad to worse. Spoke to customer service who stated that the invoice was correct. I sent my complaint to the COE, not acknowledge by him , then had it referred back to customer service. Customer service sent me an email asking me what the issue was. (I had attached this to my e-mail ((to CEO)) all details. Since then I have had two demands for payment, together with other emails. Today I have spent over 2 hours on the phone and web chat and got absolutely nowhere. Told in email to contact Ofgen. Could go on but I'm sure you know where this is going. My husband and I are elderly and my husband is disabled. This is making us ill.
