Pathetic cellphone services

Ackerman's has the worse service when it comes to electronics & mobile any electrical things nothing lasts more then 3 months, I bought a phone that phone didn't even last a year I just lost the slip so I bought a newbphone 3 months phone is problematic had to take the phone back and of course their policy is a turnaround time of abriddiculous 21 days are they having so many fautlty phoned that they need 21 days because that's what u get told, the store , neither the customer care has a number for these repair people they are using , they communicating via email , but the repair guys don't bother to even respond too the emails,howbcan you not have a number when you are entrusting your stock into their hands, so no communication , no replacement phone for the 21 days wait so you sit with no phone for 21;days that you payed for but can't use..cherry on the cake if they cantbfix it the give you a new phone but the same make as the faulty one so how many 21 days am I going to wait for phones that I regret because it seems its *******..and according to other customers PeP does the same its ridiculous something needs to be done and changed...
