Unwilling and incapable of placing order

After waiting for almost 8 months for a fixed land line, I placed an order for a SmartHome Advanced package in January. Staff at the Mall@Reds shop later told me that the order was placed incorrectly, which they then cancelled. After a 7-day waiting period (9 Feb), I placed the order again at the Mall@Reds and I was told that installation would take place \within 7 to 21 working days\". On the basis of this promise, I cancelled my existing data contract. On 14 March (> 21 working days) the call centre told me that the order had been cancelled, as it was placed incorrectly (again). Since then I have been to the shop at the Mall@Reds on 2 occasions, made 6 telephone calls to them (all went unanswered) and one email to the store manager, which all have gone without response and action. On 14th and 15th, staff promised me that somebody would get back to me with a progress update, but on both occasions failed to do so. The staff and the store manager (Algernon Matthews) are clearly both unwilling and incapable of helping me to resolve this matter. I now require your urgent assistance to get this resolved VERY URGENTLY, as I cannot afford to wait any longer. I still have no order now!"
