No telephone or bad telephone service

I have been trying to speak to a person via the telephone at Leroy Merlin for the past few hours. Only once in all this time did a person pick up, her name was Bianca. Bianca said she was unable to assist me with my query but that there were 4 gentlemen on the floor who could assist and either she or one of them would "call me right back". that was and hour and a half ago. I have been unsuccessful in reaching anyone teleponically since then. I really think the lease they can do is have a person answer their phones and have staff ready to assist customer with queries.
