Poor customer service and Zero quality customer satisfaction.

I have never been so frustrated with a service provider like I have with Capin. I think this caught me off guard also because I have known them to be previously efficient but clearly not over the phone and just online. I called in April to get assistance in changing my collection date, spoke to a consultant and they had advised that instruction had been sent. After not receiving a new mandate to accept on my bank app I called back to let them know of the situation, I was told an escalation would be made and that I should get feedback in 24hrz. I waited and called back after proposed turnaround time. After calling again I was then advised that I should go into the bank as this is not their problem. I advised that the bank, which I did and after my visit to the bank I called again to advise that bank will not be able to assist if the instruction is not sent from their end. From there onwards all I got from Capfin consultants was that there is an error on their end and matter has been escalated to IT department and they are awaiting feedback which will take 48hrs and that I will be called to receive news of the escalation. since April till today the 25th June no one ever called me to give back but instead I would be the one calling all the time only to be told the same thing and that a team leader or manager would call back which never happened. Today I spoke to three different people asking for feedback on my case only to get the same result. When I called the 4th time and demanded help. Suddenly mandate instruction was going to be sent to me. I then still advised that I want to know why it took two months for this to be done and want a supervisor to call me and explain this delay. I am very upset and will not stop calling them until my customer satisfaction has been met because in all honesty this Is not acceptable and has proven a great deal of poor customer service. Zero quality customer services received from them!! defiantly not letting this one slide.
