Shocking customer service and lack of care

My card was accidentally blocked by Mukuru. This was because I have 2 pins, something the consultant did not advise me of. I called them over a week ago and they gave me a call ticket number, and told me that the my card is suspended for ***** , and that the department that deals with that will call me and ask me few questions and unblock my card. I still haven't received a call from them. When I try to call Mukuru and ask what the problem is, they just tell me I'm on the list of people that need to be called and they will call me and that I shouldn't be calling them. I desperately need my card, but they seem not to care. What is annoying the most is when I tried to get the number for the so-called ***** department, they said I can't get hold of them, only they can call me. My end of May salary is sitting in my account and I had to borrow money to get me through this month. This is really shocking.
