bad service contact number

Could day. My mom and Dad are pensioners they have called and called on numerous occasions for anyone and I mean anyone to assist. Please they get peanuts as a pension and I expect you assist with the matter as a matter of urgency. They hold for hours and then they get off. Where the hell do you expect them to hold on with that little bit of money they receive. Stop taking old people for granted. The service has since been cancelled in which we received cancellation number. Please ensure that you collect your equipment as a matter of urgency and that no extra monies will be deducted from or even a damn account sent to them. It will not be paid and please note that If this not sorted I will take you to the Unbudsman, Devi or Shahaam Ramkissoon and believe you will loose clients and that is'nt a threat. I needed this to be sorted out ASAP. They dont know what to do and that is why I am getting involved and I feel it is ridiculous. My contact number is ***.
