Poor Customer Service

On Friday 22 May I app**** for the "May Big Deal". I was told that the fibre will be installed within 7 days. In the store I made sure that they had the correct contact number, and even received an sms statjng that my contact number was updated (to the correct one) On Tuesday 26/05 I called in to find out if I was approved and if they can tell me when the fibre will be installed. I was told that they actually had an appointment to install it on the Monday but that they could not get hold of me. I then asked them what number they used and was told that it was the 083 number. This number has been cancelled for 2 years now and, as I said before, I made sure in store that they had the correct number. So, again I confirmed my correct number and asked them to send the installers again. On Wednesday I sent an email to ***, again confirming my correct contact number and requesting the installers to come. To date, I havr not had a reply on this email. On Thursday 28/05 I receive a call (on my correct number) enquiring if I still want the fibre to be installed as it was sent back due to them not being able to get hkmd of me. I confirmed again, that I still want the fibre and that they should be sent back to me for installation. On Monday 01/06 I called 3x to find out what is going on with my order, as it has now been 9 days and I was told that installation will be done within 7 days. Only to be told al 3 times that thr system is down and they cannot check to see the progress. On Tuesday 02/06 10 days after, I called again. Just to be told again, that thr system is still down. I enquired if it is not possible for then to just call the installers to enquire when they will be coming to me, and again I am told that the system is down and they cannot contact the installers directly. I mean really. The installers work for you, you pay their salary, why is it that you can not contact them??
