It's hard to find a more inadequate guarantor. They seem to be aware of their lack of competition in terms of conditions, but the quality of service and support is simply terrible. Deals fall through, and the support team behaves rudely. With each new owner, the situation only worsens. If there's a way to do without Telderi, don't even think about it! They definitely deserve an award for the worst guarantor in the CIS.
