Pathetic service

Good day I have been emailing Old Mutual about my policy ***0(Greenlight) since a month ago about my maturity savings that was paid out. My savings maturing of R19 782.94 was paid on 4 May 2022. It was short of a R3K which I asked Old Mutual to provide me with a statement for me to see the charges that was taken as I was supposed to get the full maturity value. They have not responded after several emails to their service center and their complaints department. I asked for statements on 6th, 11th, 24th May and 1st June and have had no response only automated emails to say that they have received my emails. Nicole Jacobs has in the complaints department has also responded to my emails to investigate it but no statement has been sent till today. This is unacceptable as I am a pensioner and that R3K was taken off my savings with no record or reason for it? I would like you to assist in regard with this? The lowest rating is also not what they should get as their service is unacceptable whenever I need assistance one has to call into the call center which takes hours to answer while one is calling from a cell phone. There is no what's app no for service which other companies have if you want assistance. Kindly urgently help in this regard. Charmaine
