Bad Experience with M-WEB

I'm having a difficult and a frustrating experience with M-web, I have a 100gb monthly LTE data deal with M-web on the 30th of March I contacted them to seek help with a blocked sim card which required a PUK code since the code that came with the sim was not working, the agent I was engaging with advised me that the department that can help have closed since it was on Saturday and advised me that all will be sorted out on the 1 April 2019. Monday came and I had to call them again later on Monday around 16h00 and again reported that the they noted down all the info and sent it to the relevant dept. and I still did not get the PUK number for my sim card. I tried phoning again on the 2nd April and had to hold the line for 40 minutes before I could get through and spoke to an agent again, and they said I must try to phone in the mornings. I'm frustrated at this point for the time and money I spent trying to get a PUK number from them, Need urgent assistance since by business is suffering from Saturday. The ref. number
