R10 000 Deposit paid and still no service!

Our Geyser burst over the weekend. I received a quotation from Hidrou-Land Monday afternoon, and paid the full deposit (over R10 000) by Tuesday. To date no effort has been made to contact me or to set up a date to replace the Geyser. The only response I receive from Hidrou-Land is vague messages like \we'll get back to you"or \""we'll see if we can squeeze you in somewhere\"". AWeek with a burst Geyser is unacceptable"
