Poor service delivery

i had to firstly call them every time my claim needed to be processed or move to the different stages, then after i called them again to make a order for my headset,after 3day called and i found out that my their supplier had no stock, then they put another order , called the next day and status was not changed. now i have to wait for two weeks for them to deliver at my work address simply because from the experience i have received so far i am confident that even next week they will not deliver . now i have put the order on hold as i will not be available to to receive the order in the next two weeks, i m sure i will regret the decision as i will have to call them every day from the 8th and still i am confident it will be delivered after a week or two if i will ever.
