Speedpoint problem.

I've been having problems with my absa speedpoints for the past 1 week. I've called xlink who have sent a technician out on 2 occasions. Turns out the problem lies with absa as the speedpoint software or some **** was updated. I've been informed to call absa for the problem. I've tried calling numerous times but my calls jus get cut. This is becoming very frustrating as I run a super market and i am losing business as a result of non operational speedpoints. Melanie from absa is well aware of my problem but nothing is being done about it. She is unreachable or chooses not to take my calls.

Please fix this problem or I will be forced to change my bank and speedpoint s!
