No spares for my vacuum for 4 months

I received the Hoover HWD21 as a gift. I have needed to purchase spare bags since the beginning of March. I called in March and was told the bags would be back in stock by the end of the month. There was still no stock by the end of April. I phoned again and was told that there would be stock by the middle of June. I have just phoned again to be told that there will now only be stock by the end of July. I have been unable to vacuum for 4 months now because this company is incapable of stocking paper bags and the staff are either lying or ***********.
