Apparently too busy to handle client queries

I have had such terrible service from storage cube from day one and I am ever sorry I went ahead with my storage application. First the sales rep got the list of contents wrong and sent the incorrect size cube to us which meant I had to take two cubes as opposed to one, I am now paying for two. Then accounts only debited for the 1 cube for three months as opposed to the two, setting me back R900. I have now requested that the 1 cube be cancelled due to financial difficulty and have emailed and called numerous times but 2 weeks later still no feedback. TOM the FINANCIAL MANAGER who is apparently the only one who can give an answer is far too busy to reply to me it seems. I have been inconvenienced by storage cube on more than one occasion. your service is pathetic and I will be cancelling my contract with you, This behaviour is disgusting and I will not be disrespected this. Us clients, who pay you to store our goods pay you salary month end, DONT FORGET THAT! I will tell everyone I can not to ever do business with storage cube!
