Bangladesh will formally complain to the ICC over claims of biased umpiring and “unbearable” sledging in the first Test against South Africa, officials said. 

The side was furious after several close calls went against them in Durban, where they remained competitive for most of the match before a batting collapse saw them dismissed for 53 in the second innings. Players have since taken issue with their opponents for on-field taunts they said crossed the line into abuse.
