DIS-CHEM Very Very Bad service

Some phone numbers on the internet do not work I wanted to speak to a manager, and after 4 calls, I was not put through and only to the complaints call center, who refused to transfer me to a senior manager but said that she would call me back within 30 mins. This call back and undertaking to email me her name did not take place the call time and number I have available The manager in the store was rude and not helpful, as well as some other issues I have experienced this numerous times at Dis=chem. The product I need is listed on the website and is needed urgently .It is now 5 days and nothing has been done. Why do managers hide behind call centers?
