Telkom Mobile spend limit

TELKOM have no complaints center, no complaints email and no empathy for the client. In fact, their own employees told me to go to social media to complain. After I've changed a contract's maximum spending limit to R20, they have increased it on more than one occasion. This eventually resulted in a R1000 bill when my daughter went overseas and roaming was on. TELKOM cannot provide me with the person, transaction or time that my limit was changed. This is plain ****************.
