Deceptive coverup by A&G

Woke up to a l leaking geyser today. Contact A&G on Only to be told that I am not covered for geyser. I was then told by the call centre agent, Saleh, that the geyser cover was "accidentally" removed from my policy in October 2015, when I had lodged a claim, which I subsequently cancelled - so in essence there was no claim paid out. I then spoke to manager, Kalay, who said that I had not been paying for geyser cover since they "accidentally" removed it from my policy, as my premium had decreased. I call this a load of hogwash as I was called by the A&G Nedbank representative and was sold a policy identical in cover to my previous policy at a lower premium, hence the decrease in premium. They tried to cover up by saying my premium was reduced cos the geyser cover was removed. I have never been more appalled my the web of lies being spun to cover up their mess up! I a,m now being told that my premium will increase, but they will want to negotiate a reduction with their retention so department,. Personally I do not want to be retained as a client by a deceptive company, who after admitting their mistake, still now expect me to pay for it!!!
