Ackermans Cellphone Warrenty Repair Delay

post for ackermans managerment team I am very disgusted in the manner my cellphone in warrenty repair are being dealt with, i purchase the cell phone in 20.06.2018 The phone had problems and due to the warrenty, the phone had been taken back to the store with all the original items, The phone was returned to the dealer and, i have been making numerouse calls to the store who in return tells me that they also waiting on the dealer as they only advised it is being under repair, and they have to wait. the warrenty policy states that your repair can take up to 21 days and september till date is more than 21 days already, i am very disappointed in the service i am receiveing and so are many out there and i feel it with you all, i need the Management of Ackermans to seriousely look into my query and speed up expidite the process as clearly they have a very unreliable source they are buysing there goods from as they not adhering to there own terms and conditions.
