Excessive heat in Ackerman's Soshanguve plaza

Good day There's a problem if excessive heat in our Ackerman's shops here in Soshanguve, the Ackerman's in thorntree and Soshanguve crossing are also having that problem but the worse shop is the Ackerman's in Soshanguve plaza, opposite mabopane station. The heat is so unbearable it's impossible to stay longer and do shopping, I'm starting to doubt that Ackerman's is complying with the occupational health and safety Act. Please help.
