Santam giving false and invalid quote

Santam phoned me this morning about insurance for my home contents and i do have insurance so they offered me double more the claim amount on my home contents and a lower premium than i have with my current insurance that made my day and i was happy with it after they sent me documents i went through it and noticed that my home adress and insured amount was incorrect to what the guy told me so i phoned them to correct it after that they phoned me back with stories and the premium amount then turned double. I would not suggest this insurance company to anyone . This is unacceptble and very bad customer service
