Very poor client service!!!!!! Awaiting their call for a week now after case was opened

After a couple of days trying to contact Supersonic as I am about to move to a new address and need y fibre transferred I eventually got through to a person that could not help me but opened a case for me (case CAS-110897-T4Q6H8) - he promised me someone will give me a call but to no avail. I work from home and can not be without internet access. I once help on for more than an hour without assistance - very poor client service!!!!!!! If they do not get back to me I am going to approach a new service provider
