3 months claim on provident fund No payment yet

I so annoyed and frustrated by old mutual,Use work there till I resigned in September this year,it's been 3 months and I haven't got my provident fund,They don't update me,I have to use my airtime to call and they take you from one department to another,The call center agent cannot resolve your problem,the team leader is nowhere to be found,They keep telling me that a team leader will call me and resolve my issue but guess what those people don't care as long as they get paid,You will wait till u call them again with your own airtime,What is going on with Old Mutual such a big company is failing so much,It's like a 6 months old company,The customer care is terrible,It's been 3 months since i put my claim and no straight answer they keep telling me about authorizer getting error,Technical team will resolve then you wait 2 weeks no answer,When you call they said it's resolved money will be paid in 3 to 5 working days,Then u call back again they tell you about the error again tax is not deducted from the claim,you wait again,They tell you about authorizer gain having an error,What's wrong with this company,it take 1 day to resolve Technical error not days or weeks,Why are you failing your customers so much,It's like you don't know what you doing anymore,I will never recommend old mutual to anyone,I'm so defeated wow
